Mozilla Firefox is an open source web browser from the Mozilla Foundation in the U.S. Mozilla Firefox ESR is Firefox (Enterprise Edition). Mozilla Firefox and Mozilla Firefox ESR suffer from a buffer overflow vulnerability that stems from the fact that, under certain circumstances, untrusted input streams are copied to the stack buffer without checking their size. An attacker could use this vulnerability to cause a potentially exploitable crash that could lead to a sandbox escape.
