Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-1701)

A flaw was found in the way Firefox generated Certificate Request Message Format (CRMF) requests. An attacker could use this flaw to perform cross-site scripting (XSS) attacks or execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-1710)

A flaw was found in the way Firefox handled the interaction between frames and browser history. An attacker could use this flaw to trick Firefox into treating malicious content as if it came from the browser history, allowing for XSS attacks. (CVE-2013-1709)

It was found that the same-origin policy could be bypassed due to the way Uniform Resource Identifiers (URI) were checked in JavaScript. An attacker could use this flaw to perform XSS attacks, or install malicious add-ons from third-party pages. (CVE-2013-1713)

It was found that web workers could bypass the same-origin policy. An attacker could use this flaw to perform XSS attacks. (CVE-2013-1714)

It was found that, in certain circumstances, Firefox incorrectly handled Java applets. If a user launched an untrusted Java applet via Firefox, the applet could use this flaw to obtain read-only access to files on the user's local system. (CVE-2013-1717)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jeff Gilbert, Henrik Skupin, moz_bug_r_a4, Cody Crews, Federico Lanusse, and Georgi Guninski as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 17.0.8 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 17.0.8 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox packages.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the CentOS 5 / 6 : firefox (CESA-2013:1140) vulnerability:

Metasploit: exploit/multi/browser/firefox_tostring_console_injection
[Firefox toString console.time Privileged Javascript Injection]
Metasploit: exploit/multi/browser/firefox_proto_crmfrequest
[Firefox 5.0 - 15.0.1 exposedProps XCS Code Execution]
