CVE-2026-6331 HMAC zero-length tag forgery in EVP_DigestVerifyFinal

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...

CVE-2026-6331

CVE-2026-6331 describes an HMAC zero-length tag forgery in EVP_DigestVerifyFinal. The OpenSSL-compatibility HMAC verify path allowed a zero-length or truncated tag to pass because the signature length check only ensured it did not exceed the MAC length. The fixed behavior now requires the supplie...

The PKCS7 decode path ignores the caller-supplied output buffer size outputSz, allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release...

CVE-2026-6681 PKCS#7 decode ignores caller output buffer size, writing past buffer bounds

The PKCS7 decode path ignores the caller-supplied output buffer size outputSz, allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...
