Debian DLA-1596-1 : squid3 security update

High Nessus Plugin ID 119153


The remote Debian host is missing a security update.


It was discovered that there can be a denial of service (DoS) vulnerability in squid3 due to a memory leak in SNMP query rejection code when SNMP is enabled. In environments where per-process memory restrictions are not enforced strictly, a remote attacker to consume all memory available to the Squid process, causing it to crash.

For Debian 8 'Jessie', this problem has been fixed in version 3.4.8-6+deb8u6.

We recommend that you upgrade your squid3 packages.

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.


Upgrade the affected packages.
