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:
https://vulners.com/cve/CVE-2014-6272
(* Security fix *)
