CVE-2006-2413

Status: ModifiedMedium (5)—💥 Exploit

GNUnet before SVN revision 2781 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an empty UDP datagram, possibly involving FIONREAD errors.

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.
