Security update for MozillaFirefox
SUSE Security Update: Security update for MozillaFirefox
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
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. (MFSA 2012-27 / CVE-2012-0474)
*
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. (MFSA 2012-28 /
CVE-2012-0475)
*
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. (MFSA 2012-29 / CVE-2012-0477)
*
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. (MFSA 2012-30 /
CVE-2012-0478)
*
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. (MFSA 2012-31 / CVE-2011-3062)
*
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. (MFSA 2012-32 / CVE-2011-1187)
*
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. (MFSA
2012-33 / CVE-2012-0479)
