The browser engine in Mozilla Firefox 4.x through 5, SeaMonkey 2.x before 2.3, Thunderbird before 6, and possibly other products does not properly implement JavaScript, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.

Mozilla SeaMonkey suite was updated to version 2.3.

The update fixes bugs and security issues. Following security issues were fixed:

dbg114-seamonkey-5024 new_updateinfo seamonkey-5024 Miscellaneous memory safety hazards (rv:4.0) Mozilla identified and fixed several memory safety bugs in the browser engine used in SeaMonkey 2.2 and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

Aral Yaman reported a WebGL crash which affected SeaMonkey 2.2.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

USN-1192-1 provided Firefox 6 as a security upgrade. Unfortunately, this caused a regression in libvoikko which caused Firefox to crash while spell checking words with hyphens. This update corrects the issue. We apologize for the inconvenience.

Aral Yaman discovered a vulnerability in the WebGL engine. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2989)

Vivekanand Bolajwar discovered a vulnerability in the JavaScript engine. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2991)

Bert Hubert and Theo Snelleman discovered a vulnerability in the Ogg reader. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2991)

Robert Kaiser, Jesse Ruderman, Gary Kwong, Christoph Diehl, Martijn Wargers, Travis Emmitt, Bob Clary, and Jonathan Watt discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2985)

Rafael Gieschke discovered that unsigned JavaScript could call into a script inside a signed JAR. This could allow an attacker to execute arbitrary code with the identity and permissions of the signed JAR. (CVE-2011-2993)

Michael Jordon discovered that an overly long shader program could cause a buffer overrun. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2988)

Michael Jordon discovered a heap overflow in the ANGLE library used in Firefox's WebGL implementation. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2987)

It was discovered that an SVG text manipulation routine contained a dangling pointer vulnerability. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-0084)

Mike Cardwell discovered that Content Security Policy violation reports failed to strip out proxy authorization credentials from the list of request headers. This could allow a malicious website to capture proxy authorization credentials. Daniel Veditz discovered that redirecting to a website with Content Security Policy resulted in the incorrect resolution of hosts in the constructed policy.
This could allow a malicious website to circumvent the Content Security Policy of another website. (CVE-2011-2990).

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

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

USN-1192-1 fixed vulnerabilities in Firefox. This update provides an updated Mozvoikko for use with Firefox 6.

Aral Yaman discovered a vulnerability in the WebGL engine. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2989)

Vivekanand Bolajwar discovered a vulnerability in the JavaScript engine. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2991)

Bert Hubert and Theo Snelleman discovered a vulnerability in the Ogg reader. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2991)

Robert Kaiser, Jesse Ruderman, Gary Kwong, Christoph Diehl, Martijn Wargers, Travis Emmitt, Bob Clary, and Jonathan Watt discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2985)

Rafael Gieschke discovered that unsigned JavaScript could call into a script inside a signed JAR. This could allow an attacker to execute arbitrary code with the identity and permissions of the signed JAR. (CVE-2011-2993)

Michael Jordon discovered that an overly long shader program could cause a buffer overrun. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2988)

Michael Jordon discovered a heap overflow in the ANGLE library used in Firefox's WebGL implementation. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2987)

It was discovered that an SVG text manipulation routine contained a dangling pointer vulnerability. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-0084)

Mike Cardwell discovered that Content Security Policy violation reports failed to strip out proxy authorization credentials from the list of request headers. This could allow a malicious website to capture proxy authorization credentials. Daniel Veditz discovered that redirecting to a website with Content Security Policy resulted in the incorrect resolution of hosts in the constructed policy.
This could allow a malicious website to circumvent the Content Security Policy of another website. (CVE-2011-2990).

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