CVE-2016-6823

Status: ModifiedHigh (7.5)—

Integer overflow in the BMP coder in ImageMagick before 7.0.2-10 allows remote attackers to cause a denial of service (crash) via crafted height and width values, which triggers an out-of-bounds write.

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).
