iceweasel - several vulnerabilities

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

• CVE-2008-2798
  Devon Hubbard, Jesse Ruderman and Martijn Wargers discovered
  crashes in the layout engine, which might allow the execution of
  arbitrary code.
• CVE-2008-2799
  Igor Bukanov, Jesse Ruderman and Gary Kwong discovered crashes in
  the Javascript engine, which might allow the execution of arbitrary code.
• CVE-2008-2800
  “moz_bug_r_a4” discovered several cross-site scripting vulnerabilities.
• CVE-2008-2801
  Collin Jackson and Adam Barth discovered that Javascript code
  could be executed in the context of signed JAR archives.
• CVE-2008-2802
  “moz_bug_r_a4” discovered that XUL documents can escalate
  privileges by accessing the pre-compiled “fastload” file.
• CVE-2008-2803
  “moz_bug_r_a4” discovered that missing input sanitising in the
  mozIJSSubScriptLoader.loadSubScript() function could lead to the
  execution of arbitrary code. Iceweasel itself is not affected, but
  some addons are.
• CVE-2008-2805
  Claudio Santambrogio discovered that missing access validation in
  DOM parsing allows malicious web sites to force the browser to
  upload local files to the server, which could lead to information
  disclosure.
• CVE-2008-2807
  Daniel Glazman discovered that a programming error in the code for
  parsing .properties files could lead to memory content being
  exposed to addons, which could lead to information disclosure.
• CVE-2008-2808
  Masahiro Yamada discovered that file URLS in directory listings
  were insufficiently escaped.
• CVE-2008-2809
  John G. Myers, Frank Benkstein and Nils Toedtmann discovered that
  alternate names on self-signed certificates were handled
  insufficiently, which could lead to spoofings secure connections.
• CVE-2008-2811
  Greg McManus discovered a crash in the block reflow
  code, which might allow the execution of arbitrary code.

For the stable distribution (etch), these problems have been fixed in
version 2.0.0.15-0etch1.

Iceweasel from the unstable distribution (sid) links dynamically
against the xulrunner library.

We recommend that you upgrade your iceweasel package.
