critical Nessus Plugin ID 92748

Language:

Synopsis

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

Description

An update for squid is now available for Red Hat Enterprise Linux 6.

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.

Security Fix(es) :

* It was found that the fix for CVE-2016-4051 released via RHSA-2016:1138 did not properly prevent the stack overflow in the munge_other_line() function. A remote attacker could send specially crafted data to the Squid proxy, which would exploit the cachemgr CGI utility, possibly triggering execution of arbitrary code.
(CVE-2016-5408)

Red Hat would like to thank Amos Jeffries (Squid) for reporting this issue.

Solution

Update the affected squid and / or squid-debuginfo packages.
