|Gentoo Linux Security Advisory
Title: cpio: Directory traversal vulnerability (GLSA 200506-16)
Date: June 20, 2005
cpio contains a flaw which may allow a specially crafted cpio archive to extract files to an arbitrary directory.
cpio is a file archival tool which can also read and write tar files.
Vulnerable: < 2.6-r3
Unaffected: >= 2.6-r3
Architectures: All supported architectures
A vulnerability has been found in cpio that can potentially allow a cpio archive to extract its files to an arbitrary directory of the creator's choice.
An attacker could create a malicious cpio archive which would create files in arbitrary locations on the victim's system. This issue could also be used in conjunction with a previous race condition vulnerability (CAN-2005-1111) to change permissions on files owned by the victim.
There is no known workaround at this time.
All cpio users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3"
