Hi,
I don't want to make too much noise, so:
Although there hasn't been much time lately and the temperatures
contributed to it, I still have the following updates in the queue:
rsync 3.2.3 => Update to 3.2.3
zstd => 1.4.5 (new package, required for rsync)
Having in mind - could be ready perhaps on weekend:
libidn => Update to 1.36
libgcrypt => Update to 1.8.6
Is there any "room" for these updates or shall I wait? ;-)
Best,
Matthias

ovpnmain.cgi delivers now 'tls-version-min 1.2' for Roadwarrior and N2N.
Since the server needs it only on server side, this patch do not includes it for Roadwarrior clients.
N2N do not uses push options therefor this directive will be included on both sides.
To integrate the new directive into actual working OpenVPN server environment, the following commands
should be executed via update.sh.
Code block start:
if test -f "/var/ipfire/ovpn/server.conf"; then
# Add tls-version-minimum to OpenVPN server if not already there
if ! grep -q '^tls-version-min' /var/ipfire/ovpn/server.conf > /dev/null 2>&1; then
# Stop server before append the line
/usr/local/bin/openvpnctrl -k
# Append new directive
echo >> "tls-version-min 1.2" /var/ipfire/ovpn/server.conf
# Make sure server.conf have the correct permissions to prevent such
# --> https://community.ipfire.org/t/unable-to-start-the-openvpn-server/2465/54?u…
# case
chown nobody:nobody /var/ipfire/ovpn/server.conf
# Start server again
/usr/local/bin/openvpnctrl -s
fi

-
-x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
-32-bit PC-relative branches. Grub2 should treat R_X86_64_PLT32 as
-R_X86_64_PC32.

-Subject: Fix packed-not-aligned error on GCC 8
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When building with GCC 8, there are several errors regarding packed-not-aligned.
-
-./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]
-
-This patch fixes the build error by cleaning up the ambiguity of placing
-aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
-grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
-has to be packed, to ensure the structure is bit-to-bit mapped to the format

-Subject: xfs: Accept filesystem with sparse inodes
-
-The sparse inode metadata format became a mkfs.xfs default in
-xfsprogs-4.16.0, and such filesystems are now rejected by grub as
-containing an incompatible feature.
-
-In essence, this feature allows xfs to allocate inodes into fragmented
-freespace. (Without this feature, if xfs could not allocate contiguous
-space for 64 new inodes, inode creation would fail.)
-
-In practice, the disk format change is restricted to the inode btree,
-which as far as I can tell is not used by grub. If all you're doing
-today is parsing a directory, reading an inode number, and converting
-that inode number to a disk location, then ignoring this feature
-should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED
-
-I did some brief testing of this patch by hacking up the regression
-tests to completely fragment freespace on the test xfs filesystem, and
-then write a large-ish number of inodes to consume any existing
-contiguous 64-inode chunk. This way any files the grub tests add and
-traverse would be in such a fragmented inode allocation. Tests passed,
-but I'm not sure how to cleanly integrate that into the test harness.

+Subject: yylex: Make lexer fatal errors actually be fatal
+
+When presented with a command that can't be tokenized to anything
+smaller than YYLMAX characters, the parser calls YY_FATAL_ERROR(errmsg),
+expecting that will stop further processing, as such:
+
+ #define YY_DO_BEFORE_ACTION \
+ yyg->yytext_ptr = yy_bp; \
+ yyleng = (int) (yy_cp - yy_bp); \
+ yyg->yy_hold_char = *yy_cp; \
+ *yy_cp = '\0'; \
+ if ( yyleng >= YYLMAX ) \
+ YY_FATAL_ERROR( "token too large, exceeds YYLMAX" ); \
+ yy_flex_strncpy( yytext, yyg->yytext_ptr, yyleng + 1 , yyscanner); \
+ yyg->yy_c_buf_p = yy_cp;
+
+The code flex generates expects that YY_FATAL_ERROR() will either return
+for it or do some form of longjmp(), or handle the error in some way at
+least, and so the strncpy() call isn't in an "else" clause, and thus if
+YY_FATAL_ERROR() is *not* actually fatal, it does the call with the
+questionable limit, and predictable results ensue.
+
+Unfortunately, our implementation of YY_FATAL_ERROR() is:
+
+ #define YY_FATAL_ERROR(msg) \
+ do { \
+ grub_printf (_("fatal error: %s\n"), _(msg)); \
+ } while (0)
+
+The same pattern exists in yyless(), and similar problems exist in users
+of YY_INPUT(), several places in the main parsing loop,
+yy_get_next_buffer(), yy_load_buffer_state(), yyensure_buffer_stack,
+yy_scan_buffer(), etc.
+
+All of these callers expect YY_FATAL_ERROR() to actually be fatal, and
+the things they do if it returns after calling it are wildly unsafe.
+

+Subject: safemath: Add some arithmetic primitives that check for
+ overflow
+
+This adds a new header, include/grub/safemath.h, that includes easy to
+use wrappers for __builtin_{add,sub,mul}_overflow() declared like:
+
+ bool OP(a, b, res)
+
+where OP is grub_add, grub_sub or grub_mul. OP() returns true in the
+case where the operation would overflow and res is not modified.
+Otherwise, false is returned and the operation is executed.
+
+These arithmetic primitives require newer compiler versions. So, bump
+these requirements in the INSTALL file too.

+Date: Mon, 15 Jun 2020 12:28:27 -0400
+Subject: malloc: Use overflow checking primitives where we do
+ complex allocations
+
+This attempts to fix the places where we do the following where
+arithmetic_expr may include unvalidated data:
+
+ X = grub_malloc(arithmetic_expr);
+
+It accomplishes this by doing the arithmetic ahead of time using grub_add(),
+grub_sub(), grub_mul() and testing for overflow before proceeding.
+
+Among other issues, this fixes:
+ - allocation of integer overflow in grub_video_bitmap_create()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_png_decode_image_header()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_squash_read_symlink()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_ext2_read_symlink()
+ reported by Chris Coulson,
+ - allocation of integer overflow in read_section_as_string()
+ reported by Chris Coulson.
+
+Fixes: CVE-2020-14309, CVE-2020-14310, CVE-2020-14311

+Subject: font: Do not load more than one NAME section
+
+The GRUB font file can have one NAME section only. Though if somebody
+crafts a broken font file with many NAME sections and loads it then the
+GRUB leaks memory. So, prevent against that by loading first NAME
+section and failing in controlled way on following one.

+Subject: lzma: Make sure we don't dereference past array
+
+The two dimensional array p->posSlotEncoder[4][64] is being dereferenced
+using the GetLenToPosState() macro which checks if len is less than 5,
+and if so subtracts 2 from it. If len = 0, that is 0 - 2 = 4294967294.
+Obviously we don't want to dereference that far out so we check if the
+position found is greater or equal kNumLenToPosStates (4) and bail out.
+
+N.B.: Upstream LZMA 18.05 and later has this function completely rewritten
+without any history.

+Subject: term: Fix overflow on user inputs
+
+This requires a very weird input from the serial interface but can cause
+an overflow in input_buf (keys) overwriting the next variable (npending)
+with the user choice:
+
+(pahole output)
+
+struct grub_terminfo_input_state {
+ int input_buf[6]; /* 0 24 */
+ int npending; /* 24 4 */ <- CORRUPT
+ ...snip...
+
+The magic string requires causing this is "ESC,O,],0,1,2,q" and we overflow
+npending with "q" (aka increase npending to 161). The simplest fix is to
+just to disallow overwrites input_buf, which exactly what this patch does.

+Subject: tftp: Do not use priority queue
+
+There is not need to reassemble the order of blocks. Per RFC 1350,
+server must wait for the ACK, before sending next block. Data packets
+can be served immediately without putting them to priority queue.
+
+Logic to handle incoming packet is this:
+ - if packet block id equal to expected block id, then
+ process the packet,
+ - if packet block id is less than expected - this is retransmit
+ of old packet, then ACK it and drop the packet,
+ - if packet block id is more than expected - that shouldn't
+ happen, just drop the packet.
+
+It makes the tftp receive path code simpler, smaller and faster.
+As a benefit, this change fixes CID# 73624 and CID# 96690, caused
+by following while loop:
+
+ while (cmp_block (grub_be_to_cpu16 (tftph->u.data.block), data->block + 1) == 0)
+
+where tftph pointer is not moving from one iteration to another, causing
+to serve same packet again. Luckily, double serving didn't happen due to
+data->block++ during the first iteration.

+Subject: relocator: Protect grub_relocator_alloc_chunk_addr()
+ input args against integer underflow/overflow
+
+Use arithmetic macros from safemath.h to accomplish it. In this commit,
+I didn't want to be too paranoid to check every possible math equation
+for overflow/underflow. Only obvious places (with non zero chance of
+overflow/underflow) were refactored.

+Subject: relocator: Protect grub_relocator_alloc_chunk_align()
+ max_addr against integer underflow
+
+This commit introduces integer underflow mitigation in max_addr calculation
+in grub_relocator_alloc_chunk_align() invocation.
+
+It consists of 2 fixes:
+ 1. Introduced grub_relocator_alloc_chunk_align_safe() wrapper function to perform
+ sanity check for min/max and size values, and to make safe invocation of
+ grub_relocator_alloc_chunk_align() with validated max_addr value. Replace all
+ invocations such as grub_relocator_alloc_chunk_align(..., min_addr, max_addr - size, size, ...)
+ by grub_relocator_alloc_chunk_align_safe(..., min_addr, max_addr, size, ...).
+ 2. Introduced UP_TO_TOP32(s) macro for the cases where max_addr is 32-bit top
+ address (0xffffffff - size + 1) or similar.

+Subject: script: Avoid a use-after-free when redefining a
+ function during execution
+
+Defining a new function with the same name as a previously defined
+function causes the grub_script and associated resources for the
+previous function to be freed. If the previous function is currently
+executing when a function with the same name is defined, this results
+in use-after-frees when processing subsequent commands in the original
+function.
+
+Instead, reject a new function definition if it has the same name as
+a previously defined function, and that function is currently being
+executed. Although a behavioural change, this should be backwards
+compatible with existing configurations because they can't be
+dependent on the current behaviour without being broken.

+Subject: relocator: Fix grub_relocator_alloc_chunk_align() top
+ memory allocation
+
+Current implementation of grub_relocator_alloc_chunk_align()
+does not allow allocation of the top byte.
+
+Assuming input args are:
+ max_addr = 0xfffff000;
+ size = 0x1000;
+
+And this is valid. But following overflow protection will
+unnecessarily move max_addr one byte down (to 0xffffefff):
+ if (max_addr > ~size)
+ max_addr = ~size;
+
+~size + 1 will fix the situation. In addition, check size
+for non zero to do not zero max_addr.

+Subject: efi: fix some malformed device path arithmetic errors.
+
+Several places we take the length of a device path and subtract 4 from
+it, without ever checking that it's >= 4. There are also cases where
+this kind of malformation will result in unpredictable iteration,
+including treating the length from one dp node as the type in the next
+node. These are all errors, no matter where the data comes from.
+
+This patch adds a checking macro, GRUB_EFI_DEVICE_PATH_VALID(), which
+can be used in several places, and makes GRUB_EFI_NEXT_DEVICE_PATH()
+return NULL and GRUB_EFI_END_ENTIRE_DEVICE_PATH() evaluate as true when
+the length is too small. Additionally, it makes several places in the
+code check for and return errors in these cases.

+Subject: Fix a regression caused by "efi: fix some malformed
+ device path arithmetic errors"
+
+This commit introduced a bogus check inside copy_file_path to
+determine whether the destination grub_efi_file_path_device_path_t
+was valid before anything was copied to it. Depending on the
+contents of the heap buffer, this check could fail which would
+result in copy_file_path returning early.
+
+Without any error propagated to the caller, make_file_path would
+then try to advance the invalid device path node with
+GRUB_EFI_NEXT_DEVICE_PATH, which would also fail, returning a NULL
+pointer that would subsequently be dereferenced.
+
+Remove the bogus check, and also propagate errors from copy_file_path.

+Subject: efi: Fix use-after-free in halt/reboot path
+
+commit 92bfc33db984 ("efi: Free malloc regions on exit")
+introduced memory freeing in grub_efi_fini(), which is
+used not only by exit path but by halt/reboot one as well.
+As result of memory freeing, code and data regions used by
+modules, such as halt, reboot, acpi (used by halt) also got
+freed. After return to module code, CPU executes, filled
+by UEFI firmware (tested with edk2), 0xAFAFAFAF pattern as
+a code. Which leads to #UD exception later.
