Package : cpio Vulnerability : several Problem type : local (remote) Debian-specific: no CVE ID : CAN-2005-1111 CAN-2005-1229 Debian Bug : 306693 305372
Two vulnerabilities have been discovered in cpio, a program to manage archives of files. The Common Vulnerabilities and Exposures project identifies the following problems:
CAN-2005-1111
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.
CAN-2005-1229
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.
