- Update of rootfile
- Changelog
Release 2.4.5 Fri February 18 2022
Security fixes:
#562 CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
sequences (e.g. from start tag names) to the XML
processing application on top of Expat can cause
arbitrary damage (e.g. code execution) depending
on how invalid UTF-8 is handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#561 CVE-2022-25236 -- Passing (one or more) namespace separator
characters in "xmlns[:prefix]" attribute values
made Expat send malformed tag names to the XML
processor on top of Expat which can cause
arbitrary damage (e.g. code execution) depending
on such unexpectable cases are handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#558 CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
that could be triggered by e.g. a 2 megabytes
file with a large number of opening braces.
Expected impact is denial of service or potentially
arbitrary code execution.
#560 CVE-2022-25314 -- Fix integer overflow in function copyString;
only affects the encoding name parameter at parser creation
time which is often hardcoded (rather than user input),
takes a value in the gigabytes to trigger, and a 64-bit
machine. Expected impact is denial of service.
#559 CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
needs input in the gigabytes and a 64-bit machine.
Expected impact is denial of service or potentially
arbitrary code execution.
Other changes:
#557 #564 Version info bumped from 9:4:8 to 9:5:8;
see https://verbump.de/ for what these numbers do
