Description

Memory safety bugs were reported in Firefox 49 and Firefox ESR 45.4.

This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.

Techniques & Countermeasures

  • CWE-119•Improper Restriction of Operations within the Bounds of a Memory Buffer

    The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
