Name of the Vulnerable Software and Affected Versions Firefox versions prior to 64 Firefox ESR versions prior to 60.4 Thunderbird versions prior to 60.4

Description A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit, resulting in a potentially exploitable crash. The issue is related to a buffer overflow in the Skia library, which may allow a remote attacker to execute arbitrary code or cause a denial of service.
