CVE-2024-25714

CRITICAL

Rhonabwy < 1.1.13 - Timing Side-Channel Attack via HMAC Signature Verification

Title source: llm

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.)
