CVE-2004-0247

Status: ModifiedMedium (5)—💥 Exploit

The client and server of Chaser 1.50 and earlier allow remote attackers to cause a denial of service (crash via exception) via a UDP packet with a length field that is greater than the actual data length, which causes Chaser to read unexpected memory.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Base score: 5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 3.44%
Percentile among all scored CVEs: 89
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.
