CVE-2024-25714
Last modified
CVE-2024-25714 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.). EPSS estimates a 0.81% chance of exploitation in the next 30 days.
