Detail

Several vulnerabilities have been discovered in unarj, a non-free ARJ unarchive utility. The Common Vulnerabilities and Exposures Project identifies the following vulnerabilities:

CAN-2004-0947

A buffer overflow has been discovered when handling long file names contained in an archive. An attacker could create a specially crafted archive which could cause unarj to crash or possibly execute arbitrary code when being extracted by a victim.

CAN-2004-1027

A directory traversal vulnerability has been found so that an attacker could create a specially crafted archive which would create files in the parent directory when being extracted by a victim. When used recursively, this vulnerability could be used to overwrite critical system files and programs.

For the stable distribution (woody) these problems have been fixed in version 2.43-3woody1.

For the unstable distribution (sid) these problems don't apply since unstable/non-free does not contain the unarj package.

We recommend that you upgrade your unarj package.

Id Description
11695 unarj Filename Handling Overflow
10788 unarj Traversal Arbitrary File Overwrite

The unarj utility has been reported to have a vulnerability related to traversal style attacks (/../) and uncompressing an archive. As reported, this would allow an attacker to overwrite any file the victim user has permission to write to. unarj (or tar or zip) allows full/absolute paths in archives and could be used in the same fashion, regardless of using traversal notation. This is a non-issue.
