Mandriva Linux Security Advisory MDVSA-2015:017
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libevent
Date : January 8, 2015
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated libevent packages fix security vulnerability:

Andrew Bartlett of Catalyst reported a defect affecting certain
applications using the Libevent evbuffer API. This defect leaves
applications which pass insanely large inputs to evbuffers open
to a possible heap overflow or infinite loop. In order to exploit
this flaw, an attacker needs to be able to find a way to provoke the
program into trying to make a buffer chunk larger than what will fit
into a single size_t or off_t (CVE-2014-6272).
