CVE-2007-1948

Status: ModifiedHigh (9.3)—💥 Exploit

Buffer overflow in IrfanView 3.99 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via the (1) xoffset or (2) yoffset RLE command, or (3) large non-RLE encoded blocks in a crafted BMP image, as demonstrated by rle8of3.bmp and rle8of4.bmp.

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.
