Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated squid packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 7.

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

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

It was found that Squid configured with client-first SSL-bump did not correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a Squid server using a specially crafted X.509 certificate. (CVE-2015-3455)

This update fixes the following bugs :

* Previously, the squid process did not handle file descriptors correctly when receiving Simple Network Management Protocol (SNMP) requests. As a consequence, the process gradually accumulated open file descriptors. This bug has been fixed and squid now handles SNMP requests correctly, closing file descriptors when necessary.
(BZ#1198778)

* Under high system load, the squid process sometimes terminated unexpectedly with a segmentation fault during reboot. This update provides better memory handling during reboot, thus fixing this bug.
(BZ#1225640)

Users of squid are advised to upgrade to these updated packages, which fix these bugs. After installing this update, the squid service will be restarted automatically.

Solution

Update the affected squid packages.
