Fedora Core 2 : unarj-2.63a-7 (2004-414)

Critical Nessus Plugin ID 62247


The remote Fedora Core host is missing a security update.


A buffer overflow bug has been discovered in unarj when handling long file names contained in an archive. An attacker could create an archive with a specially crafted path which could cause unarj to crash or execute arbitrary instructions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0947 to this issue.

Additionally, a path traversal vulnerability exists in unarj which allows an attacker to extract files to the parent ('..') directory.
When used recursively, this vulnerability can be used to overwrite critical system files and programs.

Users of unarj are advised to upgrade to these packages.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected unarj package.
