Debian: DSA-3641-2 High: Firefox-ESR Memory Leak Vulnerabilities

Multiple security issues have been found in the Mozilla Firefox web
browser: Multiple memory safety errors, buffer overflows and other
implementation errors may lead to the execution of arbitrary code,
cross-site scriping, information disclosure and bypass of the same-origin
policy.

For the stable distribution (jessie), these problems have been fixed in
version 45.3.0esr-1~deb8u1.

For the unstable distribution (sid), these problems have been fixed in
version 45.3.0esr-1 for firefox-esr and 48.0-1 for firefox.

We recommend that you upgrade your firefox-esr packages.
