All supported architectures
ClamAV has many security flaws which make it vulnerable to remote execution
of arbitrary code and a Denial of Service.
ClamAV is a GPL anti-virus toolkit, designed for integration with mail
servers to perform attachment scanning. ClamAV also provides a command
line scanner and a tool for fetching updates of the virus database.
ClamAV has multiple security flaws: a boundary check was performed
incorrectly in petite.c, a buffer size calculation in unfsg_133 was
incorrect in fsg.c, a possible infinite loop was fixed in tnef.c and a
possible infinite loop in cabd_find was fixed in cabd.c . In addition
to this, Marcin Owsiany reported that a corrupted DOC file causes a
segmentation fault in ClamAV.
By sending a malicious attachment to a mail server that is hooked with
ClamAV, a remote attacker could cause a Denial of Service or the
execution of arbitrary code.
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-0.87.1"
