Ubuntu 11.04 : clamav vulnerability (USN-1179-1)

Medium Nessus Plugin ID 55729


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


It was discovered that the hash processing code in libclamav improperly handled messages with certain hashes. This could allow a remote attacker to craft a document 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.
