Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser: Multiple memory safety errors, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code, the bypass of security restrictions or denial of service.

For the stable distribution (wheezy), these problems have been fixed in version 31.3.0esr-1~deb7u1. For the upcoming stable distribution (jessie), these problems will be fixed soon. For the unstable distribution (sid), these problems have been fixed in version 31.3.0esr-1. We recommend that you upgrade your iceweasel packages.

Iceweasel is Firefox, rebranded. It is a powerful, extensible web browser with support for modern web application technologies.
