• Weakness: 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 products

• Debian Linux: 11.0, 12.0
• Rhonabwy Project Rhonabwy: through 1.1.3
