- 漏洞讨论

The 'unalz' tool contains a vulnerability in the handling of pathnames for archived files.

By specifying a path for an archived item that points outside the expected destination directory, the creator of the archive can cause the file to be extracted to arbitrary locations on the filesystem, possibly including paths containing system binaries and other sensitive or confidential information.

Presumably, an attacker could use this to create or overwrite binaries in any desired location, using the privileges of the invoking user.

Version 0.53 is vulnerable; other versions may also be affected.

- 漏洞利用

An exploit is not required.

- 解决方案

The vendor has released version 0.55 to address this issue.
