Package : iceape
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-3982 CVE-2012-3986 CVE-2012-3990 CVE-2012-3991
CVE-2012-4179 CVE-2012-4180 CVE-2012-4182 CVE-2012-4186
CVE-2012-4188

Several vulnerabilities have been discovered in Iceape, an internet
suite based on Seamonkey:

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
Icedove 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
Icedove 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.

Additionally, this update fixes a regression in the patch for
CVE-2012-3959, released in DSA-2554-1.

For the stable distribution (squeeze), these problems have been fixed in
version 2.0.11-16.

For the testing distribution (wheezy), these problems have been fixed in
version 10.0.10esr-1.

For the unstable distribution (sid), these problems have been fixed in
version 10.0.10esr-1.

We recommend that you upgrade your iceape packages.

[DSA 2571-1] libproxy security update
- -------------------------------------------------------------------------
Debian Security Advisory DSA-2571-1 security@debian.org
http://www.debian.org/security/ Raphael Geissert

Package : libproxy
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-4505

The Red Hat Security Response Team discovered that libproxy, a library
for automatic proxy configuration management, applied insufficient
validation to the Content-Length header sent by a server providing a
proxy.pac file. Such remote server could trigger an integer overflow
and consequently overflow an in-memory buffer.

For the stable distribution (squeeze), this problem has been fixed in
version 0.3.1-2+squeeze1.

For the testing distribution (wheezy), and the unstable distribution
(sid), this problem has been fixed in version 0.3.1-5.1.

We recommend that you upgrade your libproxy packages.
