Synopsis ========
ClamAV has many security flaws which make it vulnerable to remote execution of arbitrary code and a Denial of Service.
Background ==========
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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.87.1 >= 0.87.1
Description ===========
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.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ClamAV users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.87.1"
