gnutls: gnutls: Information disclosure via heap overread in RSA key exchange

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

gnutls: gnutls: Authentication Bypass via NUL Character in Username

A flaw was found in gnutls. Servers configured with RSA-PSK Rivest–Shamir–Adleman – Pre-Shared Key wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass...
