Astra Linux – Vulnerability in gnutls28

A NULL pointer dereference flaw was discovered in GnuTLS. Since Nettle’s hash update functions internally call memcpy, using zero-length inputs may lead to undefined behavior. This flaw can result in a denial of service after authentication in rare circumstances...

Astra Linux – Vulnerability in gnutls28

A vulnerability was identified: the response times for malformed ciphertexts in RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding...

Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

Astra Linux – Vulnerability in gnutls28

A vulnerability was discovered in GnuTLS. The response times to malformed ciphertexts in the RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack during the RSA-PSK key exchange,...
