Weaknesses
CWE-1255, CWE-203

Description

In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attacks, because it stops the comparison when the first difference is spotted in the two signatures. (The fix uses gnutls_memcmp, which has constant-time execution.)

Affected configurations

• rhonabwy project rhonabwy (<= 1.1.3) • debian debian linux 11.0 • debian debian linux 12.0
