{"id":"UBUNTU-CVE-2025-32990","details":"A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.","modified":"2026-04-22T15:38:02.144648Z","published":"2025-07-10T10:15:00Z","related":["USN-7635-1","USN-7742-1"],"upstream":["CVE-2025-32990"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-32990"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-32990"},{"type":"REPORT","url":"https://lists.gnupg.org/pipermail/gnutls-help/2025-July/004883.html"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-32990"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7635-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7742-1"}],"affected":[{"package":{"name":"gnutls28","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.4.10-4ubuntu1.9+esm2?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.10-4ubuntu1.9+esm2"}]}],"versions":["3.3.15-5ubuntu2","3.3.18-1ubuntu1","3.3.20-1ubuntu1","3.4.9-2ubuntu1","3.4.10-4ubuntu1","3.4.10-4ubuntu1.1","3.4.10-4ubuntu1.2","3.4.10-4ubuntu1.3","3.4.10-4ubuntu1.4","3.4.10-4ubuntu1.5","3.4.10-4ubuntu1.6","3.4.10-4ubuntu1.7","3.4.10-4ubuntu1.8","3.4.10-4ubuntu1.9","3.4.10-4ubuntu1.9+esm1"],"ecosystem_specific":{"availability":"Available
