Changes between 3.0.15 and 3.0.16 [11 Feb 2025]
CVE-2024-13176[1] - Fixed timing side-channel in ECDSA signature
computation.
There is a timing signal of around 300 nanoseconds when the top word of
the 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 is affected. To be able to measure this
leak, the attacker process must either be located in the same physical
computer or must have a very fast network connection with low latency.
CVE-2024-9143[2] - Fixed possible OOB memory access with invalid
low-level GF(2^m) elliptic curve parameters.
Use of the low-level GF(2^m) elliptic curve APIs with untrusted explicit
values for the field polynomial can lead to out-of-bounds memory reads
or writes. Applications working with "exotic" explicit binary (GF(2^m))
curve parameters, that make it possible to represent invalid field
polynomials with a zero constant term, via the above or similar APIs,
may terminate abruptly as a result of reading or writing outside of
array bounds. Remote code execution cannot easily be ruled out.
