GNU Transport Layer Security Library 3.8.7.1
Posted Aug 15, 2024
Authored by Simon Josefsson, Nikos Mavrogiannopoulos | Site gnu.org

GnuTLS is a secure communications library implementing the SSL and TLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols, as well as APIs to parse and write X.509, PKCS #12, OpenPGP, and other required structures. It is intended to be portable and efficient with a focus on security and interoperability.

Changes: New configure option to compile out DSA support in libgnutls. Experimental support added for X25519Kyber768Draft00 key exchange in TLS in libgnutls. No modifications to API or ABI.

It is intended to be portable and efficient with a focus on security and interoperability.

Changes: RSA-OAEP encryption scheme is now supported. Fixed side-channel in the deterministic ECDSA. Fixed a bug where certtool crashed when verifying a certificate chain with more than 16 certificates. Compression libraries are now loaded dynamically as needed instead of all being loaded during gnutls library initialization. The gnutls library can now be linked with the static library of GMP.

It is intended to be portable and efficient with a focus on security and interoperability.

Changes: Added option to disable RSAES-PKCS1-v1_5. Added support for RIPEMD160 and PBES1-DES-SHA1 for backward compatibility with GCR. A couple of memory related issues have been fixed in RSA PKCS#1 v1.5 decryption error handling and deterministic ECDSA with earlier versions of GMP. Fixed a bug where building gnutls statically failed due to a duplicate definition of nettle_rsa_compute_root_tr().

It is intended to be portable and efficient with a focus on security and interoperability.

Changes: libgnutls had multiple security fixes. They fixed more timing side-channel issues inside RSA-PSK key exchange. They fixed an assertion failure when verifying a certificate chain with a cycle of cross signatures. Fixed a regression in handling Ed25519 keys stored in PKCS#11 token certtool that was unable to handle Ed25519 keys generated on PKCS#11 with pkcs11-tool (OpenSC). This is a regression introduced in 3.8.2.
