TITLE:
Urgent Backup ZIP Processing Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA39699

VERIFY ADVISORY:
http://secunia.com/advisories/39699/

DESCRIPTION:
Lincoln has discovered a vulnerability in Urgent Backup, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing
ZIP archives. This can be exploited to cause a stack-based buffer
overflow by tricking a user into restoring files from a specially
crafted ZIP file.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 3.20. Other versions may
also be affected.

SOLUTION:
Do not process untrusted ZIP files.

PROVIDED AND/OR DISCOVERED BY:
