CVE-2026-60108

[CVE catalog]

Zeek before 8.0.9 contains an uncontrolled memory consumption vulnerability in the FTP analyzer that allows unauthenticated remote attackers to cause process termination by sending a crafted FTP control session negotiating AUTH GSSAPI followed by a large ADAT control line. Attackers can exploit the NVT_Analyzer component's lack of a maximum line length check, causing it to continuously double its internal buffer without bounds during base64 decoding of an attacker-controlled ADAT token, resulting in denial of service of the Zeek sensor.
