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

Summary:

AdvanceCOMP could be made to crash or run programs if it opened a specially
crafted file.

Software Description:

Details:

malformed zip files. If a user or automated system were tricked into
processing a specially crafted zip file, a remote attacker could cause

execute arbitrary code.
