Description OSIDB Bzimport 2025-04-15 01:32:18 UTC

A heap-buffer-overflow (off-by-one) vulnerability exists in the template parsing logic within the
certtool utility of GnuTLS. The vulnerability specifically occurs when parsing certain multiline
configuration options from a user-supplied template file, allowing an attacker to cause an
out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and potential
denial-of-service (DoS).
