advancecomp vulnerability

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

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

Software description

Joonun Jang discovered that AdvanceCOMP incorrectly handled certain
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.
