[DSA846] DSA-846-1 cpio

Vulnerability Assessment Summary
DSA-846-1 cpio

Detailed Explanation for this Vulnerability Assessment

Two vulnerabilities have been discovered in cpio, a program to manage
archives of files. The Common Vulnerabilities and Exposures project
identifies the following problems:
Imran Ghory discovered a race condition in setting the file
permissions of files extracted from cpio archives. A local
attacker with write access to the target directory could exploit
this to alter the permissions of arbitrary files the extracting
user has write permissions for.
Imran Ghory discovered that cpio does not sanitise the path of
extracted files even if the --no-absolute-filenames option was
specified. This can be exploited to install files in arbitrary
locations where the extracting user has write permissions to.
For the old stable distribution (woody) these problems have been fixed in
version 2.4.2-39woody2.
For the stable distribution (sarge) these problems have been fixed in
version 2.5-1.3.
For the unstable distribution (sid) these problems have been fixed in
version 2.6-6.
We recommend that you upgrade your cpio package.
