Fedora 40: clamav 2024-e8f7a74693 Security Advisory Updates
Summary
Clam AntiVirus is an anti-virus toolkit for UNIX. The main purpose of this
software is the integration with mail servers (attachment scanning). The
package provides a flexible and scalable multi-threaded daemon, a command
line scanner, and a tool for automatic updating via Internet. The programs
are based on a shared library distributed with the Clam AntiVirus package,
which you can use with your own software. The virus database is based on
the virus database from OpenAntiVirus, but contains additional signatures
(including signatures for popular polymorphic viruses, too) and is KEPT UP
TO DATE.
Update Information:
Update to 1.0.7 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. 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.
