iceweasel - several

Multiple vulnerabilities have been discovered in Iceweasel, Debian’s
version of the Mozilla Firefox web browser. The Common
Vulnerabilities and Exposures project identifies the following
problems:

• CVE-2012-3982:

Multiple unspecified vulnerabilities in the browser engine
allow remote attackers to cause a denial of service (memory
corruption and application crash) or possibly execute
arbitrary code via unknown vectors.

• CVE-2012-3986:

Iceweasel does not properly restrict calls to DOMWindowUtils
methods, which allows remote attackers to bypass intended
access restrictions via crafted JavaScript code.

• CVE-2012-3990:

A Use-after-free vulnerability in the IME State Manager
implementation allows remote attackers to execute arbitrary
code via unspecified vectors, related to the
nsIContent::GetNameSpaceID function.

• CVE-2012-3991:

Iceweasel does not properly restrict JSAPI access to the
GetProperty function, which allows remote attackers to bypass
the Same Origin Policy and possibly have unspecified other
impact via a crafted web site.

• CVE-2012-4179:

A use-after-free vulnerability in the
nsHTMLCSSUtils::CreateCSSPropertyTxn function allows remote
attackers to execute arbitrary code or cause a denial of
service (heap memory corruption) via unspecified vectors.

• CVE-2012-4180:

A heap-based buffer overflow in the
nsHTMLEditor::IsPrevCharInNodeWhitespace function allows
remote attackers to execute arbitrary code via unspecified
vectors.

• CVE-2012-4182:

A use-after-free vulnerability in the
nsTextEditRules::WillInsert function allows remote attackers
to execute arbitrary code or cause a denial of service (heap
memory corruption) via unspecified vectors.

• CVE-2012-4186:

A heap-based buffer overflow in the
nsWav-eReader::DecodeAudioData function allows remote attackers
to execute arbitrary code via unspecified vectors.

• CVE-2012-4188:

A heap-based buffer overflow in the Convolve3x3 function
allows remote attackers to execute arbitrary code via
unspecified vectors.

For the stable distribution (squeeze), these problems have been fixed
in version 3.5.16-19.

For the testing distribution (wheezy) and the unstable distribution
(sid), these problems have been fixed in version 10.0.8esr-1.

We recommend that you upgrade your iceweasel packages.
