CVE-2026-60108
Description
A flaw was found in Zeek. An uncontrolled memory consumption vulnerability in the FTP analyzer allows unauthenticated remote attackers to cause a denial of service. This occurs when a crafted FTP control session with a large ADAT control line is sent, exploiting the NVT_Analyzer component's lack of a maximum line length check. The component continuously doubles its internal buffer without bounds during base64 decoding, leading to process termination of the Zeek sensor.

Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
