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.
