Vulnerability Assessment Details

[DSA959] DSA-959-1 unalz

Vulnerability Assessment Summary
DSA-959-1 unalz

Detailed Explanation for this Vulnerability Assessment

Ulf H�rnhammar from the Debian Security Audit Project discovered that unalz, a
decompressor for ALZ archives, performs insufficient bounds checking
when parsing file names. This can lead to arbitrary code execution if
a possible hacker provides a crafted ALZ archive.
The old stable distribution (woody) does not contain unalz.
For the stable distribution (sarge) this problem has been fixed in
version 0.30.1
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you upgrade your unalz package.
