Hello Michael, Hello Matthias, Hello list,
Hello everyone,
I just received this announcement that clamav 0.104.0 has been released.
The interesting things for us are the changes in the build system:
It now requires cmake which isn’t a problem
It now requires LLVM which we don’t have
LLVM is probably going to be large, but Stefan has already played around with it and we might be able to merge his patches. So, Stefan, could you please post them? I suppose Matthias is the de-facto maintainer of clamav. You will need to merge these patches locally to see if clamav is happy with what Stefan has built.
I've created and pushed a new LLVM git branch in my personal git repository, which builds the LLVM compiler suite.
https://git.ipfire.org/?p=people/stevee/ipfire-2.x.git;a=shortlog;h=refs/hea...
I hope this will do the trick with the new clamav version.
Best regards,
-Stefan
This will be an interesting project :)
-Michael

ClamAV 0.104.0 releasedClamAV 0.104.0 is available as an official release as of today. We are also announcing a new Long Term Support (LTS) program today in an update to our End-of-Life (EOL) policy. The LTS will start retroactively with ClamAV 0.103, the previous feature release. This new LTS policy extends the life of 0.103 up through September 2023 and will facilitate the production of more frequent feature releases while enabling users to rely on a supported version for years to come if they cannot keep pace with the feature release cadence. For full details about the Long Term Support program, you can see the LTS announcement blog post and review the LTS policy in our online documentation. We're also introducing new install packages to make it easier for folks to upgrade without having to build ClamAV from source and without having to wait for a community volunteer to package the latest release. You can find the new install packages on the ClamAV.net Downloads Page. Today you can find: * x86_64 and i686 RPM packages compatible with RPM-based Linux distributions running glibc version 2.17 or newer. * x86_64 and i686 DEB packages compatible with Debian-based Linux distributions running glibc version 2.23 or newer. * An x86_64/ARM64 macOS installer package is compatible with Intel and Apple M1 systems. * x64 and win32 Windows packages are compatible with Windows 7 and newer. In the future, we hope to supplement these with ARM64 Linux DEB and RPM packages and an x86_64 FreeBSD package. Please note that you may find installations in this release require more manual configuration than when using a preconfigured package provided by a Linux or Unix distribution. See our installation instructions on clamav.net for more information. ClamAV 0.104.0 includes the following improvements and changes.
New Requirements * As of ClamAV 0.104, CMake is required to build ClamAV.We have added comprehensive build instructions for using CMake to the new INSTALL.md file. The online documentation will also be updated to include CMake build instructions.The Autotools and the Visual Studio build systems have been removed.
Major changes * The built-in LLVM for the bytecode runtime has been removed.The bytecode interpreter is the default runtime for bytecode signatures just as it was in ClamAV 0.103.We hoped to add support for newer versions of LLVM, but ran out of time. If you're building ClamAV from source and you wish to use LLVM instead of the bytecode interpreter, you will need to supply the development libraries for LLVM version 3.6.2. See the "bytecode runtime" section in INSTALL.md to learn more. * There are now official ClamAV images on Docker Hub.Docker Hub ClamAV tags:clamav/clamav:<version>: A release preloaded with signature databases.Using this container will save the ClamAV project some bandwidth. Use this if you will keep the image around so that you don't download the entire database set every time you start a new container. Updating with FreshClam from the existing databases set does not use much data.clamav/clamav:<version>_base: A release with no signature databases.Use this container only if you mount a volume in your container under /var/lib/clamav to persist your signature database databases. This method is the best option because it will reduce data costs for ClamAV and for the Docker registry, but it does require advanced familiarity with Linux and Docker.Caution: Using this image without mounting an existing database directory will cause FreshClam to download the entire database set each time you start a new container.You can use the unstable version (i.e. clamav/clamav:unstable or clamav/clamav:unstable_base) to try the latest from our development branch.Please, be kind when using 'free' bandwidth, both for the virus databases but also the Docker registry. Try not to download the entire database set or the larger ClamAV database images on a regular basis.For more details, see the ClamAV Docker documentation.Special thanks to Olliver Schinagl for his excellent work creating ClamAV's new Docker files, image database deployment tooling, and user documentation. * clamd and freshclam are now available as Windows services. To install and run them, use the --install-service option and net start [name] command.Special thanks to Gianluigi Tiesi for his original work on this feature.
Notable changesThe following was added in 0.103.1 and is repeated here for awareness, as patch versions do not generally introduce new options: * Added a new scan option to alert on broken media (graphics) file formats. This feature mitigates the risk of malformed media files intended to exploit vulnerabilities in other software. At present, media validation exists for JPEG, TIFF, PNG and GIF files. To enable this feature, set AlertBrokenMedia yes in clamd.conf, or use the --alert-broken-media option when using clamscan. These options are disabled by default in this patch release but may be enabled in a subsequent release. Application developers may enable this scan option by enabling CL_SCAN_HEURISTIC_BROKEN_MEDIA for the heuristic scan option bit field. * Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing behavior. BMP and JPEG 2000 files will continue to detect as CL_TYPE_GRAPHICS because ClamAV does not yet have BMP or JPEG 2000 format checking capabilities. * Added progress callbacks to libclamav for:database load: cl_engine_set_clcb_sigload_progress()engine compile: cl_engine_set_clcb_engine_compile_progress()engine free: cl_engine_set_clcb_engine_free_progress()These new callbacks enable an application to monitor and estimate load, compile, and unload progress. See clamav.h for API details. * Added progress bars to ClamScan for the signature load and engine compile steps before a scan begins. The start-up progress bars won't be enabled if ClamScan isn't running in a terminal (i.e. stdout is not a TTY), or if any of these options are used:- -debug--quiet--infected--no-summary Other improvements * Added the %f format string option to the ClamD VirusEvent feature to insert the file path of the scan target when a virus-event occurs. This supplements the VirusEvent %v option which prints the signature (virus) name. The ClamD VirusEvent feature also provides two environment variables, $CLAM_VIRUSEVENT_FILENAME and $CLAM_VIRUSEVENT_VIRUSNA ME for a similar effect. Patch courtesy of Vasile Papp. * Improvements to the AutoIt extraction module. Patch courtesy of cw2k. * Added support for extracting images from Excel *.xls (OLE2) documents. * Trusted SHA256-based Authenticode hashes can now be loaded in from *.cat files. For more information, visit our Authenticode documentation about using *.cat files with *.crb rules to trust signed Windows executables.
Bug fixes * Fixed a memory leak affecting logical signatures that use the "byte compare" feature. Patch courtesy of Andrea De Pasquale. * Fixed bytecode match evaluation for PDF bytecode hooks in PDF file scans. * Other minor bug fixes.
