[slackware-security] libevent (SSA:2016-085-01)

New libevent packages are available for Slackware 14.1 and -current to
fix security issues.


Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/libevent-2.0.22-i486-1_slack14.1.txz: Upgraded.
Multiple integer overflows in the evbuffer API allow context-dependent
attackers to cause a denial of service or possibly have other unspecified
impact via "insanely large inputs" to the (1) evbuffer_add,
(2) evbuffer_expand, or (3) bufferevent_write function, which triggers a
heap-based buffer overflow or an infinite loop.
For more information, see:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6272
(* Security fix *)
