Description David Walser 2016-04-21 15:49:33 CEST

Upstream has issued an advisory on April 20:
http://www.squid-cache.org/Advisories/SQUID-2016_5.txt

Updated packages uploaded for Mageia 5 and Cauldron.

Note that SQUID-2016_6 (CVE-2016-405[2-4]) is also fixed, but doesn't affect us, since we disable ESI in our package.

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

Updated squid packages fix security vulnerability:

Due to incorrect buffer management Squid cachemgr.cgi tool is vulnerable to a
buffer overflow when processing remotely supplied inputs relayed to it from
Squid. This problem allows any client to seed the Squid manager reports with
data that will cause a buffer overflow when processed by the cachemgr.cgi tool
(CVE-2016-4051).
