It was discovered that GnuTLS incorrectly handled exporting Subject Alternative Name (SAN) entries containing an otherName. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-32988)
It was discovered that GnuTLS incorrectly handled parsing the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly obtain sensitive information. (CVE-2025-32989)
It was discovered that the GnuTLS certtool utility incorrectly handled parsing certain template files. An attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-32990)
Stefan Bühler discovered that GnuTLS incorrectly handled parsing certain template files. An attacker could possibly use this issue to cause GnuTLS to crash, resulting in a denial of service. (CVE-2025-6395)
