Official Description
nsZipArchive.cpp in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 accesses unintended memory locations, which allows remote attackers to have an unspecified impact via a crafted ZIP archive.

CVE-2015-2735 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
