CVE-2019-11933

Status: ModifiedCritical (9.8)—💥 PoC

A heap buffer overflow bug in libpl_droidsonroids_gif before 1.2.19, as used in WhatsApp for Android before version 2.19.291 could allow remote attackers to execute arbitrary code or cause a denial of service.

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
