CVE-2008-3794

Status: ModifiedMedium (6.8)—💥 Exploit

Integer signedness error in the mms_ReceiveCommand function in modules/access/mms/mmstu.c in VLC Media Player 0.8.6i allows remote attackers to execute arbitrary code via a crafted mmst link with a negative size value, which bypasses a size check and triggers an integer overflow followed by a heap-based buffer overflow.

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.
