24 Oct 2022 — GNU Libtasn1 before 4.19.0 has an ETYPE_OK off-by-one array size check that affects asn1_encode_simple_der. GNU Libtasn1 versiones anteriores a 4.19.0, presenta una comprobación de tamaño de matriz ETYPE_OK fuera de lugar que afecta a la función asn1_encode_simple_der An out-of-bounds read flaw was found in Libtasn1 due to an ETYPE_OK off-by-one error in the asn1_encode_simple_der() function. This flaw allows a remote attacker to pass specially crafted data or invalid values to the application, triggering a... • https://bugs.gentoo.org/866237 • CWE-125: Out-of-bounds Read CWE-193: Off-by-one Error •

22 Jan 2018 — An issue was discovered in the _asn1_decode_simple_ber function in decoding.c in GNU Libtasn1 before 4.13. Unlimited recursion in the BER decoder leads to stack exhaustion and DoS. Se ha descubierto un problema en la función _asn1_decode_simple_ber en decoding.c en GNU Libtasn1, en versiones anteriores a la 4.13. La recursión no limitada en el descodificador BER conduce al agotamiento de la pila y a DoS. It was discovered that Libtasn1 incorrectly handled certain files. • http://git.savannah.nongnu.org/cgit/libtasn1.git/commit/?id=c593ae84cfcde8fea45787e53950e0ac71e9ca97 • CWE-674: Uncontrolled Recursion •

02 Jul 2017 — The _asn1_check_identifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1_node structure. It may lead to a remote denial of service attack. La función _asn1_check_identifier en GNU Libtasn1 hasta la versión 4.12 provoca una desreferencia de puntero NULL y un cierre inesperado cuando se leen entradas manipuladas que desencadenan la asignación de un valor NULL en una estructura asn1_node.
