Debian DLA-445-2 : squid3 regression update

high Nessus Plugin ID 89045

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The backported patch to solve CVE-2016-2569 yielded to failed assertions that made squid3 to crash when closing connections. The fix for this CVE strongly relies on exception handling present in more recent versions of squid3, that I failed to identify in the previous update. I have reverted the patch to take the safest position, taking into account that Squeeze users should migrate to a supported version of Debian. This post-EOL update is intended to keep a functional squid3 package in the archive.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
