The destructor function for the "WindowsDllDetourPatcher" class can be re-purposed by malicious code in concert with another vulnerability to write arbitrary data to an attacker controlled location in memory. This can be used to bypass existing memory protections in this situation. Note: This attack only affects Windows operating systems. Other operating systems are not affected. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

This update for MozillaFirefox to ESR 52.3 fixes several issues. These security issues were fixed :

The update for icedove/thunderbird issued as DLA-1087-1 did not build on i386. This update corrects this. For reference, the original advisory text follows.

Multiple security issues have been found in the Mozilla Thunderbird mail client: Multiple memory safety errors, buffer overflows and other implementation errors may lead to the execution of arbitrary code or spoofing.

For Debian 7 'Wheezy', these problems have been fixed in version 1:52.3.0-4~deb7u2.

We recommend that you upgrade your icedove packages.
