Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : clamav vulnerability (USN-1258-1)

Medium Nessus Plugin ID 56777


The remote Ubuntu host is missing a security-related patch.


Stephane Chazelas discovered the bytecode engine of ClamAV improperly handled recursion under certain circumstances. This could allow a remote attacker to craft a file that could cause ClamAV to crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libclamav6 package.
