CVE-2022-38143

Status: ModifiedCritical (9.8)—

A heap out-of-bounds write vulnerability exists in the way OpenImageIO v2.3.19.0 processes RLE encoded BMP images. A specially-crafted bmp file can write to arbitrary out of bounds memory, which can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

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).
