GLSA-200502-32 : UnAce: Buffer overflow and directory traversal vulnerabilities

medium Nessus Plugin ID 17235

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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 (CAN-2005-0160). He also found out that UnAce is vulnerable to directory traversal attacks, if an archive contains './..' sequences or absolute filenames (CAN-2005-0161).
 Impact :

 An attacker 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.

Solution

All UnAce users should upgrade to the latest available 1.2 version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/unace-1.2b-r1'
