Mandriva Linux Security Advisory MDVSA-2015:065
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : cpio
Date : March 27, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem Description:

Updated cpio package fixes security vulnerabilities:

Heap-based buffer overflow in the process_copy_in function in GNU
Cpio 2.11 allows remote attackers to cause a denial of service via
a large block value in a cpio archive (CVE-2014-9112).

Additionally, a null pointer dereference in the copyin_link function
which could cause a denial of service has also been fixed.

In GNU Cpio 2.11, the --no-absolute-filenames option limits
extracting contents of an archive to be strictly inside a current
directory. However, it can be bypassed with symlinks. While extracting
an archive, it will extract symlinks and then follow them if they
are referenced in further entries. This can be exploited by a rogue
archive to write files outside the current directory (CVE-2015-1197).
