Details
George Pantelakis and Alicja Kario discovered that OpenSSL had a timing
side-channel when performing ECDSA signature computations. A remote
attacker could possibly use this issue to recover private data.
(CVE-2024-13176)
It was discovered that OpenSSL incorrectly handled certain memory
operations when using low-level GF(2^m) elliptic curve APIs with untrusted
explicit values for the field polynomial. When being used in this uncommon
fashion, a remote attacker could use this issue to cause OpenSSL to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2024-9143)
