More information:

Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2015-0817

  ilxu1a reported a flaw in Mozilla's implementation of typed array bounds checking in JavaScript just-in-time compilation (JIT) and its management of bounds checking for heap access. This flaw can be leveraged into the reading and writing of memory allowing for arbitary code execution on the local system.

• CVE-2015-0818

  Mariusz Mlynski discovered a method to run arbitrary scripts in a privileged context. This bypassed the same-origin policy protections by using a flaw in the processing of SVG format content navigation.

For the stable distribution (wheezy), these problems have been fixed in version 31.5.3esr-1~deb7u1.

For the unstable distribution (sid), these problems have been fixed in version 31.5.3esr-1.

We recommend that you upgrade your iceweasel packages.
