Debian DSA-3522-1 : squid3 - security update

high Nessus Plugin ID 90033
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Alex Rousskov from The Measurement Factory discovered that Squid3, a fully featured web proxy cache, does not properly handle errors for certain malformed HTTP responses. A remote HTTP server can exploit this flaw to cause a denial of service (assertion failure and daemon exit).


Upgrade the squid3 packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 3.1.20-2.2+deb7u4.

For the stable distribution (jessie), this problem has been fixed in version 3.4.8-6+deb8u2.
