A denial of service problem in Squid3 initiated via invalid Content-Length headers and memory leaks has been fixed. (CVE-2012-5643 / CVE-2013-0189, SQUID-2012:1)

Also a logrotate permission issue has been fixed.

Updated squid packages fix security vulnerability :

Due to missing input validation, the Squid cachemgr.cgi tool in Squid before 3.1.22 and 3.2.4 is vulnerable to a denial of service attack when processing specially crafted requests (CVE-2012-5643).

It was discovered that the patch for CVE-2012-5643 was incorrect. A remote attacker could exploit this flaw to perform a denial of service attack (CVE-2013-0189).

Also a logrotate permission issue has been fixed.

According to its banner, the version of Squid running on the remote host is 2.x or 3.x prior to 3.1.23 / 3.2.6 / 3.3.0.3.  The included 'cachemgr.cgi' tool reportedly lacks input validation, which could be abused by any client able to access that tool to perform a denial of service attack on the service host.

Note this fix is a result of an incomplete fix for CVE-2012-5643.
 Further note that Nessus did not actually test for this issue, but instead has relied on the version in the server's banner.
