high Nessus Plugin ID 94563

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2600 advisory.

Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects.

The following packages have been upgraded to a newer upstream version: squid (3.5.20). (BZ#1273942, BZ#1349775)

Security Fix(es):

* Incorrect boundary checks were found in the way squid handled headers in HTTP responses, which could lead to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response. (CVE-2016-2569, CVE-2016-2570)

* It was found that squid did not properly handle errors when failing to parse an HTTP response, possibly leading to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response. (CVE-2016-2571, CVE-2016-2572)

* An incorrect boundary check was found in the way squid handled the Vary header in HTTP responses, which could lead to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response. (CVE-2016-3948)

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected squid, squid-migration-script and / or squid-sysvinit packages.
