CVE-2016-5652

Status: ModifiedHigh (7)—

An exploitable heap-based buffer overflow exists in the handling of TIFF images in LibTIFF's TIFF2PDF tool. A crafted TIFF document can lead to a heap-based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.

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).
