CVE-2020-11501 (GCVE-0-2020-11501)

Vulnerability from cvelistv5

Published

Modified

2024-08-04 11:35

Severity ?

CWE

Summary

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol.
