CVE-2004-0768

Status: ModifiedHigh (7.5)—

libpng 1.2.5 and earlier does not properly calculate certain buffer offsets, which could allow remote attackers to execute arbitrary code via a buffer overflow attack.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Base score: 7.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 3.26%
Percentile among all scored CVEs: 88
Score date: 10/2/2026

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).
