Scientific Linux Security Update : squid on SL7.x x86_64
Low Nessus Plugin ID 87574
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt 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 automatically.
SolutionUpdate the affected squid, squid-debuginfo and / or squid-sysvinit packages.
