MiracleLinux 7 : squid-3.3.8-26.el7 (AXSA:2015-755:01)

medium Nessus Plugin ID 289115

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2015-755:01 advisory.

 Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests.
 Squid consists of a main server program squid, a Domain Name System lookup program (dnsserver), a program for retrieving FTP data (ftpget), and some management and client tools.
 Security issues fixed with this release:
 CVE-2015-3455 Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, does not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate.
 Fixed 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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected squid package.
