CVE-2015-0806

Status: ModifiedHigh (7.5)—

The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 attempts to use memset for a memory region of negative length during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors that trigger rendering of 2D graphics content.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
