CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Summary:
The remote host is missing an update for the 'squid' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
squid on CentOS 6

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
Squid is a high-performance proxy caching server for web clients that supports FTP, Gopher, and HTTP data objects. A denial of service flaw was found in the way the Squid Cache Manager processed certain requests. A remote attacker who is able to access the Cache Manager CGI could use this flaw to cause Squid to consume an excessive amount of memory. (CVE-2012-5643) This update also fixes the following bugs: * Due to a bug in the ConnStateData::noteMoreBodySpaceAvailable() function, child processes of Squid terminated upon encountering a failed assertion. An upstream patch has been provided and Squid child processes no longer terminate. (BZ#805879) * Due to an upstream patch, which renamed the HTTP header controlling persistent connections from 'Proxy-Connection' to 'Connection', the NTLM pass-through authentication does not work, thus preventing login. This update adds the new 'http10' option to the squid.conf file, which can be used to enable the change in the patch. This option is set to 'off' by default. When set to 'on', the NTLM pass-through authentication works properly, thus allowing login attempts to succeed. (BZ#844723) * When the IPv6 protocol was disabled and Squid tried to handle an HTTP GET request containing an IPv6 address, the Squid child process terminated due to signal 6. This bug has been fixed and such requests are now handled as expected. (BZ#832484) * The old 'stale if hit' logic did not account for cases where the stored stale response became fresh due to a successful re-validation with the origin server. Consequently, incorrect warning messages were returned. Now, Squid no longer marks elements as stale in the described scenario. (BZ#847056) * When squid Linux Distribution Packages were installed before samba-winbind, the wbpriv group did not include Squid. Consequently, NTLM authentication calls failed. Now, Squid correctly adds itself into the wbpriv group if samba-winbind is installed before Squid, thus fixing this bug. (BZ#797571) * In FIPS mode, Squid was using private MD5 hash functions for user authentication and network access. As MD5 is incompatible with FIPS mode, Squid could fail to start. This update limits the use of the private MD5 functions to local disk file hash identifiers, thus allowing Squid to work in FIPS mode. (BZ#833086) * Under high system load, the squid process could terminate unexpectedly with a segmentation fault during reboot. This update provides better memory handling during reboot, thus fixing this ... Description truncated, please see the referenced URL(s) for more information.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
