clamav vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.10

Software 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.
