ClamAV: Multiple Vulnerabilities
Gentoo Linux Security Advisory

All supported architectures
ClamAV is vulnerable to a heap-based buffer overflow potentially allowing
remote execution of arbitrary code and a Denial of Service.
ClamAV is a GPL virus scanner.
Damian Put and an anonymous researcher reported a potential heap-based
buffer overflow vulnerability in rebuildpe.c responsible for the
rebuilding of an unpacked PE file, and a possible crash in chmunpack.c
in the CHM unpacker.
By sending a malicious attachment to a mail server running ClamAV, or
providing a malicious file to ClamAV through any other method, a remote
attacker could cause a Denial of Service and potentially the execution
of arbitrary code with the permissions of the user running ClamAV.
There is no known workaround at this time.
All ClamAV users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.5"
