Last modified

CVE-2025-32990 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. 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.. EPSS estimates a 0.72% chance of exploitation in the next 30 days.
