Updated squid packages fix security vulnerabilities :

Due to incorrect state management, Squid before 3.3.12 is vulnerable to a denial of service attack when processing certain HTTPS requests if the SSL-Bump feature is enabled (CVE-2014-0128).

Matthew Daley discovered that Squid 3 did not properly perform input validation in request parsing. A remote attacker could send crafted Range requests to cause a denial of service (CVE-2014-3609).

Due to incorrect buffer management Squid can be caused by an attacker to write outside its allocated SNMP buffer (CVE-2014-6270).

Due to incorrect bounds checking Squid pinger binary is vulnerable to denial of service or information leak attack when processing larger than normal ICMP or ICMPv6 packets (CVE-2014-7141).

Due to incorrect input validation Squid pinger binary is vulnerable to denial of service or information leak attacks when processing ICMP or ICMPv6 packets (CVE-2014-7142).

The remote host is affected by the vulnerability described in GLSA-201411-11 (Squid: Multiple vulnerabilities)

    An assertion failure in processing of SSL-Bump has been found in Squid.
      Heap based overflow is discovered when processing SNMP requests.
  Impact :

    A remote attacker could send a specially crafted request, possibly       resulting in a executing of arbitrary code or Denial of Service       condition.
  Workaround :

    There is no known workaround at this time.

A flaw was found in the way Squid handled malformed HTTP Range headers. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid. (CVE-2014-3609)

A buffer overflow flaw was found in Squid's DNS lookup module. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid. (CVE-2013-4115)

Squid 3.1 before 3.3.12 and 3.4 before 3.4.4, when SSL-Bump is enabled, allows remote attackers to cause a denial of service (assertion failure) via a crafted range request, related to state management. (CVE-2014-0128)

A denial of service flaw was found in the way Squid processed certain HTTPS requests when the SSL Bump feature was enabled. A remote attacker could send specially crafted requests that could cause Squid to crash. (CVE-2014-0128)

Squid versions prior to 3.3.12 and 3.4.4 are potentially affected by a denial of service vulnerability due to a state management error within SSL-Bump.

The SSLBump feature acts as TLS/SSL termination for clients. If this feature is enabled, squid can crash with range requests, leading to a potential Denial of Service condition.

Updated squid packages fix security vulnerability :

Due to incorrect state management, Squid before 3.3.12 is vulnerable to a denial of service attack when processing certain HTTPS requests if the SSL-Bump feature is enabled (CVE-2014-0128).

Updated squid packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

A denial of service flaw was found in the way Squid processed certain HTTPS requests when the SSL Bump feature was enabled. A remote attacker could send specially crafted requests that could cause Squid to crash. (CVE-2014-0128)

Red Hat would like to thank the Squid project for reporting this issue. Upstream acknowledges Mathias Fischer and Fabian Hugelshofer from Open Systems AG as the original reporters.

All squid users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the squid service will be restarted automatically.

A remote DoS attack in the Squid web proxy has been fixed.

Due to incorrect state management, Squid was vulnerable to a denial of service attack when processing certain HTTPS requests. (CVE-2014-0128)

For more information see http://www.squid-cache.org/Advisories/SQUID-2014_1.txt .

Additionally, a bug in the logrotate configuration file has been fixed. The 'su' statement was moved into the 'logfile' section.

New upstream version with a security fix.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its banner, the version of Squid running on the remote host is 3.x prior to 3.3.12 or 3.4.4 and is, therefore, affected by a denial of service vulnerability. 

A flaw exists in SSL-Bump in regards to the state management when processing range requests.  A remote attacker can cause the server to crash with specially crafted HTTPS requests. 

Note that Nessus has relied only on the version in the proxy server's banner, which is not updated by the patch the project has released to address the issue.  If this patch has been applied properly and the service has been restarted, consider this to be a false positive.
