Vulnerability Assessment Summary
UnAce: Buffer overflow and directory traversal vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200502-32
(UnAce: Buffer overflow and directory traversal vulnerabilities)


Ulf Harnhammar discovered that UnAce suffers from buffer overflows
when testing, unpacking or listing specially crafted ACE archives
(CVE-2005-0160). He also found out that UnAce is vulnerable to
directory traversal attacks, if an archive contains "./.." sequences or
absolute filenames (CVE-2005-0161).

A possible hacker could exploit the buffer overflows to execute
malicious code or the directory traversals to overwrite arbitrary
files.

Workaround

There is no known workaround at this time.
