ClamAV: Multiple vulnerabilities ClamAV has many security flaws which make it vulnerable to remote execution of arbitrary code and a Denial of Service. clamav 2005-11-06 2006-05-22 109213 remote 0.87.1 0.87.1

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:

# emerge --sync # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.87.1"
