Ubuntu 4.10 / 5.04 : cpio vulnerabilities (USN-189-1)

medium Nessus Plugin ID 20601

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Imran Ghory found a race condition in the handling of output files.
While a file was unpacked with cpio, a local attacker with write permissions to the target directory could exploit this to change the permissions of arbitrary files of the cpio user. (CAN-2005-1111)

Imran Ghory discovered a path traversal vulnerability. Even when the
--no-absolute-filenames option was specified, cpio did not filter out '..' path components. By tricking an user into unpacking a malicious cpio archive, this could be exploited to install files in arbitrary paths with the privileges of the user calling cpio. (CAN-2005-1229).

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

Solution

Update the affected cpio package.
