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...

gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

gnutls: gnutls: Memory corruption due to off-by-one error in PKCS#12 bag handling

A flaw was found in gnutls. An off-by-one error exists in the PKCS12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of...
