This just built in Debian and it also fixed a long standing issue on sparc64 which existed since the 1.0.0 version. |

fmap_need_off_once() may return an unaligned pointer. This in return leads to an unaligned access during the load of the uint32_t variables loading to failures on architectures not supporting unaligned access. This was reported to the Debian BTS as #1073128. [bigeasy: Commit message, reworked the patch a bit].

0.103.12 (2024-09-04) ClamAV 0.103.12 is a patch release with the following fixes: - [CVE-2024-20506](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-20506): Changed the logging module to disable following symlinks on Linux and Unix systems so as to prevent an attacker with existing access to the 'clamd' or 'freshclam' services from using a symlink to corrupt system files. This issue affects all currently supported versions. It will be fixed in: - 1.4.1 - 1.3.2 - 1.0.7 - 0.103.12 Thank you to Detlef for identifying this issue. - [CVE-2024-20505](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-20505): Fixed a possible out-of-bounds read bug in the PDF file parser that could cause a denial-of-service (DoS) condition. This issue affects all currently supported versions. It will be fixed in: - 1.4.1 - 1.3.2 - 1.0.7 - 0.103.12 Thank you to OSS-Fuzz for identifying this issue. - ClamOnAcc: Fixed an infinite loop when a watched directory does not exist. - [GitHub pull request](Cisco-Talos/clamav#1198) - Fixed a bug causing CVDs downloaded by the `DatabaseCustomURL` Freshclam config option to be pruned and then re-downloaded with every update. Also added the new 'valhalla' database name to the list of optional databases in preparation for future work. - Backport of [GitHub pull request](Cisco-Talos/clamav#1233) - Fixed an unaligned pointer dereference issue on select architectures. Fix courtesy of Sebastian Andrzej Siewior. - Backport of [GitHub pull request](Cisco-Talos/clamav#1293)
