CVE-2024-13176

Name of the Vulnerable Software and Affected Versions OpenSSL (affected versions not specified)

Description A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring the timing would require either local access to the signing application or a very fast network connection with low latency. There is a timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is inverted ECDSA nonce value is zero. This can happen with significant probability only for some of the supported elliptic curves, in particular the NIST P-521 curve. The severity of this vulnerability is Low.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
