The ClamAV 1.1.0 feature release is now stable and available for download on ClamAV.net<https://www.clamav.net/downloads> or through Docker Hub<https://hub.docker.com/r/clamav/clamav/>. ClamAV 1.1.0 includes the following improvements and changes. Major changes * Added the ability to extract images embedded in HTML CSS <style> blocks. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/813 * Updated to Sigtool so that the --vba option will extract VBA code from Microsoft Office documents the same way that libclamav extracts VBA. This resolves several issues where Sigtool could not extract VBA. Sigtool will also now display the normalized VBA code instead of the pre-normalized VBA code. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/852 * Added a new ClamScan and ClamD option: --fail-if-cvd-older-than=days. Additionally, we introduce FailIfCvdOlderThan as a clamd.conf synonym for --fail-if-cvd-older-than. When passed, it causes ClamD to exit on startup with a non-zero return code if the virus database is older than the specified number of days. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/867 * Added a new function cl_cvdgetage() to the libclamav API. This function will retrieve the age in seconds of the youngest file in a database directory, or the age of a single CVD (or CLD) file. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/867 * Added a new function cl_engine_set_clcb_vba() to the libclamav API. Use this function to set a cb_vba callback function. The cb_vba callback function will be run whenever VBA is extracted from office documents. The provided data will be a normalized copy of the extracted VBA. This callback was added to support Sigtool so that it can use the same VBA extraction logic that ClamAV uses to scan documents. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/852 Other improvements * Removed the vendored TomsFastMath library in favor of using OpenSSL to perform "big number"/multiprecision math operations.

Feature courtesy of Sebastian Andrzej Siewior. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/815 * Build system: Enabled version-scripts with CMake to limit symbol exports for libclamav, libfreshclam, libclamunrar_iface, and libclamunrar shared libraries on Unix systems, excluding macOS. Improvement courtesy of Orion Poplawski and Sebastian Andrzej Siewior. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/776 * Build system: Enabled users to pass in custom Rust compiler flags using the RUSTFLAGS CMake variable. Feature courtesy of Orion Poplawski. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/835 * Removed a hard-coded alert for CVE-2004-0597. The CVE is old enough that it is no longer a threat and the detection had occasional false-positives. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/855 * Set Git attributes to prevent Git from altering line endings for Rust vendored libraries. Third-party Rust libraries are bundled in the ClamAV release tarball. We do not commit them to our own Git repository, but community package maintainers may now store the tarball contents in Git. The Rust build system verifies the library manifest, and this change ensures that the hashes are correct. Improvement courtesy of Nicolas R. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/800 * Fixed compile time warnings. Improvement courtesy of Răzvan Cojocaru. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/795 * Added a minor optimization when matching domain name regex signatures for PDB, WDB and CDB type signatures. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/837 * Build system: Enabled the ability to select a specific Python version. When building, you may use the CMake option -D PYTHON_FIND_VER=<version> to choose a specific Python version. Feature courtesy of Matt Jolly. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/787 * Added improvements to the ClamOnAcc process log output so that it is easier to diagnose bugs. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/822 * Windows: Enabled the MSI installer to upgrade between feature versions more easily when ClamAV is installed to a location different from the default (i.e., not C:\Program Files\ClamAV). This means that the MSI installer can find a previous ClamAV 1.0.x installation to upgrade to ClamAV 1.1.0. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/872 * Sigtool: Added the ability to change the location of the temp directory using the --tempdir option and added the ability to retain the temp files created by Sigtool using the --leave-temps option. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/852 * Other minor improvements. Bug fixes * Fixed the broken ExcludePUA / --exclude-pua feature. Fix courtesy of Ged Haywood and Shawn Iverson. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/780 * Fixed an issue with integer endianness when parsing Windows executables on big-endian systems. Fix courtesy of Sebastian Andrzej Siewior. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/814 * Fixed a possible stack overflow read when parsing WDB signatures. This issue is not a vulnerability. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/807 * Fixed a possible index out of bounds when loading CRB signatures. This issue is not a vulnerability. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/810 * Fixed a possible use after free when reading logical signatures. This issue is not a vulnerability. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/811 * Fixed a possible heap overflow read when reading PDB signatures. This issue is not a vulnerability. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/812 * Fixed a possible heap overflow read in javascript normalizer module. This issue is not a vulnerability. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/868 * Fixed two bugs that would cause Freshclam to fail update when applying a CDIFF database patch if that patch adds a file to the database archive or removes a file from the database archive. This bug also caused Sigtool to fail to create such a patch. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/893 * Fixed an assortment of complaints identified by Coverity static analysis. * GitHub pull requests: * https://github.com/Cisco-Talos/clamav/pull/891 * https://github.com/Cisco-Talos/clamav/pull/899 * Fixed one of the Freshclam tests that was failing on some Fedora systems due to a bug printing debug-level log messages to stdout. Fix courtesy of Arjen de Korte. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/881 * Correctly remove temporary files generated by the VBA and XLM extraction modules so that the files are not leaked in patched versions of ClamAV where temporary files are written directly to the temp-directory instead of writing to a unique subdirectory. * GitHub pull request: https://github.com/Cisco-Talos/clamav/pull/894 Acknowledgments Special thanks to the following people for code contributions and bug reports: * Arjen de Korte * Craig Andrews * Ged Haywood * Matt Jolly * Orion Poplawski * Nicolas R. * Răzvan Cojocaru * Red * Shawn Iverson * Sebastian Andrzej Siewior * The OSS-Fuzz project Posted by Micah Snyder <https://www.blogger.com/profile/07798916006145826441> at 5:07 PM<https://blog.clamav.net/2023/05/clamav-110-released.html> [https://img1.blogblog.com/img/icon18_email.gif] <https://www.blogger.com/email-post.g?blogID=2366689974368239573&postID=2525909540599416328> Email This<https://www.blogger.com/share-post.g?blogID=2366689974368239573&postID=2525909540599416328&target=email>BlogThis!<https://www.blogger.com/share-post.g?blogID=2366689974368239573&postID=2525909540599416328&target=blog>Share to Twitter<https://www.blogger.com/share-post.g?blogID=2366689974368239573&postID=2525909540599416328&target=twitter>Share to Facebook<https://www.blogger.com/share-post.g?blogID=2366689974368239573&postID=2525909540599416328&target=facebook>Share to Pinterest<https://www.blogger.com/share-post.g?blogID=2366689974368239573&postID=2525909540599416328&target=pinterest> Labels: 1.1.0<https://blog.clamav.net/search/label/1.1.0>, clamav<https://blog.clamav.net/search/label/clamav>, release<https://blog.clamav.net/search/label/release> Micah Snyder ClamAV Development Talos Cisco Systems, Inc.
