Description

An update for squid is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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) :

* 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)
