SuSE: New Firefox kernel packages fix security vulnerabilities

MozillaFirefox was updated to the 10.0.4 ESR release to fix various bugs and security issues. Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox 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. Christian Holler a reported memory safety and security problem affecting Firefox 11. Security researchers reported memory safety problems and crashes that affect Firefox ESR and Firefox 11.

Using the Address Sanitizer tool, security researcher Aki Helin from OUSPG found that IDBKeyRange of indexedDB remains in the XPConnect hashtable instead of being unlinked before being destroyed. When it is destroyed, this causes a use-after-free, which is potentially exploitable. Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG found a heap corruption in gfxImageSurface which allows for invalid frees and possible remote code execution. Anne van Kesteren of Opera Software found a multi-octet encoding issue where certain octets will destroy the following octets in the processing of some multibyte character sets. This can leave users vulnerable to cross-site scripting (XSS) attacks on maliciously crafted web pages.

Security research firm iDefense reported that researcher wushi of team509 discovered a memory corruption on Windows Vista and Windows 7 systems with hardware acceleration disabled or using incompatible video drivers. Mozilla community member Matias Juntunen discovered an error in WebGLBuffer where FindMaxElementInSubArray receives wrong template arguments from FindMaxUshortElement. This bug causes maximum index to be computed incorrectly within WebGL.drawElements, allowing the reading of illegal video memory. Security researchers Jordi Chancel and Eddy Bordi reported that they could short-circuit page loads to show the address of a different site than what is loaded in the window in the addressbar. Security researcher Chris McGowen independently reported the same flaw, and further demonstrated that this could lead to loading scripts from the attacker’s site, leaving users vulnerable to cross-site scripting (XSS) attacks.

Security researcher Simone Fabiano reported that if a cross-site XHR or WebSocket is opened on a web server on a non-standard port for web traffic while using an IPv6 address, the browser will send an ambiguous origin headers if the IPv6 address contains at least 2 consecutive 16-bit fields of zeroes. If there is an origin access control list that uses IPv6 literals, this issue could be used to bypass these access controls on the server. Security researcher Masato Kinugawa found that during the decoding of ISO-2022-KR and ISO-2022-CN character sets, characters near 1024 bytes are treated incorrectly, either doubling or deleting bytes. On certain pages it might be possible for an attacker to pad the output of the page such that these errors fall in the right place to affect the structure of the page, allowing for cross-site script (XSS) injection.

Mozilla community member Ms2ger found an image rendering issue with WebGL when texImage2D uses use JSVAL_TO_OBJECT on arbitrary objects. This can lead to a crash on a maliciously crafted web page. While there is no evidence that this is directly exploitable, there is a possibility of remote code execution. Mateusz Jurczyk of the Google Security Team discovered an off-by-one error in the OpenType Sanitizer using the Address Sanitizer tool. This can lead to an out-of-bounds read and execution of an uninitialized function pointer during parsing and possible remote code execution. Security researcher Daniel Divricean reported that a defect in the error handling of javascript errors can leak the file names and location of javascript files on a server, leading to inadvertent information disclosure and a vector for further attacks.

Security researcher Jeroen van der Gun reported that if RSS or Atom XML invalid content is loaded over HTTPS, the addressbar updates to display the new location of the loaded resource, including SSL indicators, while the main window still displays the previously loaded content. This allows for phishing attacks where a malicious page can spoof the identify of another seemingly secure site.

  An update that contains security fixes can now be
  installed. It includes two new package versions.

Description:


  MozillaFirefox was updated to the 10.0.4 ESR release to fix
  various bugs  and security issues.

  *

  Mozilla developers identified and fixed several
  memory safety bugs in the browser engine used in Firefox
  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. (MFSA
  2012-20)

  In general these flaws cannot be exploited through
  email in the Thunderbird and SeaMonkey products because
  scripting is disabled, but are potentially a risk in
  browser or browser-like contexts in those products.

  o

  Christian Holler a reported memory safety and
  security problem affecting Firefox 11. (CVE-2012-0468)

  o

  Bob Clary, Christian Holler, Brian Hackett,
  Bobby Holley, Gary Kwong, Hilary Hall, Honza Bambas, Jesse
  Ruderman, Julian Seward, and Olli Pettay reported memory
  safety problems and crashes that affect Firefox ESR and
  Firefox 11. (CVE-2012-0467)

  *

  Using the Address Sanitizer tool, security researcher
  Aki Helin from OUSPG found that IDBKeyRange of indexedDB
  remains in the XPConnect hashtable instead of being
  unlinked before being destroyed. When it is destroyed, this
  causes a use-after-free, which is potentially exploitable.
  (MFSA 2012-22 / CVE-2012-0469)

  *

  Using the Address Sanitizer tool, security researcher
  Atte Kettunen from OUSPG found a heap corruption in
  gfxImageSurface which allows for invalid frees and possible
  remote code execution. This happens due to float error,
  resulting from graphics values being passed through
  different number systems. (MFSA 2012-23 / CVE-2012-0470)

  *

  Anne van Kesteren of Opera Software found a
  multi-octet encoding issue where certain octets will
  destroy the following octets in the processing of some
  multibyte character sets. This can leave users vulnerable
  to cross-site scripting (XSS) attacks on maliciously
  crafted web pages. (MFSA 2012-24 / CVE-2012-0471)

  *

  Security research firm iDefense reported that
  researcher wushi of team509 discovered a memory corruption
  on Windows Vista and Windows 7 systems with hardware
  acceleration disabled or using incompatible video drivers.
  This is created by using cairo-dwrite to attempt to render
  fonts on an unsupported code path. This corruption causes a
  potentially exploitable crash on affected systems. (MFSA
  2012-25 / CVE-2012-0472)

  *

  Mozilla community member Matias Juntunen discovered
  an error in WebGLBuffer where FindMaxElementInSubArray
  receives wrong template arguments from
  FindMaxUshortElement. This bug causes maximum index to be
  computed incorrectly within WebGL.drawElements, allowing
  the reading of illegal video memory. (MFSA 2012-26 /
  CVE-2012-0473)

  Security researchers Jordi Chancel and Eddy Bordi
  reported that they could short-circuit page loads to show
  the address of a different site than what is loaded in the
  window in the addressbar. Security researcher Chris McGowen

  demonstrated that this could lead to loading scripts from
  the attacker's site, leaving users vulnerable to cross-site
  scripting (XSS) attacks. (MFSA 2012-27 / CVE-2012-0474)
