RHSA-2007:0245 - Low: cpio security and bug fix update

Synopsis

Low: cpio security and bug fix update

Type/Severity

Security Advisory Low

Topic

An updated cpio package that fixes a security issue and various bugs is now available.

This update has been rated as having low security impact by the Red Hat Security Response Team.

Description

GNU cpio copies files into or out of a cpio or tar archive.

A buffer overflow was found in cpio on 64-bit platforms. By tricking a user into adding a specially crafted large file to a cpio archive, a local attacker may be able to exploit this flaw to execute arbitrary code with the target user's privileges. (CVE-2005-4268)

This erratum also addresses the following bugs:

  • cpio did not set exit codes appropriately.

  • cpio did not create a ram disk properly.

All users of cpio are advised to upgrade to this updated package, which contains backported fixes to correct these issues.
