Ubuntu 9.10 / 10.04 LTS / 10.10 : clamav vulnerability (USN-1076-1)

Description

It was discovered that the Microsoft Office processing code in libclamav improperly handled certain Visual Basic for Applications (VBA) data. This could allow a remote attacker to craft a document that could crash clamav or possibly execute arbitrary code.

In the default installation, attackers would be isolated by the ClamAV AppArmor profile.

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.
