Synopsis ========
cpio contains a flaw which may allow a specially crafted cpio archive to extract files to an arbitrary directory.
Background ==========
cpio is a file archival tool which can also read and write tar files.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/cpio < 2.6-r3 >= 2.6-r3
Description ===========
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.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All cpio users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3"
