Description David Walser 2013-04-02 20:44:51 CEST

Ubuntu has issued an advisory today (April 2):
http://www.ubuntu.com/usn/usn-1784-1/

Cauldron is not affected (already fixed upstream in 1.1.28).

Patched package uploaded for Mageia 2.

Patch added to Mageia 1 SVN.

Advisory:
========================

Updated libxslt packages fix security vulnerability:

Nicholas Gregoire discovered that libxslt incorrectly handled certain empty
values. If a user or automated system were tricked into processing a
specially crafted XSLT document, a remote attacker could cause libxslt to
crash, causing a denial of service (CVE-2012-6139).

Comment 2 Dave Hodgins 2013-04-02 23:24:18 CEST

Testing complete on Mageia 2 i586 and x86_64.

Confirmed the segfault is fixed.

Could someone from the sysadmin team push the srpm
libxslt-1.1.26-6.20120127.5.mga2.src.rpm
from Mageia 2 Core Updates Testing to Core Updates.
