SuSE 10 Security Update : MozillaFirefox (ZYPP Patch Number 8154)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 10 host is missing a security-related patch.

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 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)
