squid (SL7)

Synopsis: Moderate: squid security and bug fix update
Advisory ID: SLSA-2015:2378-1
Issue Date: 2015-11-19
CVE Numbers: CVE-2015-3455

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.

* 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.

After installing this update, the squid service will be restarted
