iceweasel - several vulnerabilities

Several remote vulnerabilities have been discovered in the Iceweasel
web browser, an unbranded version of the Firefox browser. The Common
Vulnerabilities and Exposures project identifies the following problems:

• CVE-2008-2785
  It was discovered that missing boundary checks on a reference
  counter for CSS objects can lead to the execution of arbitrary code.
• CVE-2008-2933
  Billy Rios discovered that passing an URL containing a pipe symbol
  to Iceweasel can lead to Chrome privilege escalation.

For the stable distribution (etch), these problems have been fixed in
version 2.0.0.16-0etch1. Updated packages for ia64, arm and mips are
not yet available and will be released as soon as they have been built.

For the unstable distribution (sid), these problems have been fixed in
xulrunner 1.9.0.1-1 and iceweasel 3.0.1-1.

We recommend that you upgrade your iceweasel package.
