CVE-2012-0277

Status: ModifiedMedium (6.8)—💥 Exploit

Heap-based buffer overflow in XnView before 1.99 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted PCT image.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
Base score: 6.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 8.01%
Percentile among all scored CVEs: 95
Score date: 10/7/2026

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).

💥 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.
