Summary

Details

Issue summary: Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a server may fail to notice that the server was not authenticated, because handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode is set. Impact summary: TLS and DTLS connections using raw public keys may be vulnerable to man-in-middle attacks when server authentication failure is not detected by clients. RPKs are disabled by default in both TLS clients and TLS servers. The issue only arises when TLS clients explicitly enable RPK use by the server, and the server, likewise, enables sending of an RPK instead of an X.509 certificate chain. The affected clients are those that then rely on the handshake to fail when the server's RPK fails to match one of the expected public keys, by setting the verification mode to SSL_VERIFY_PEER. Clients that enable server-side raw public keys can still find out that raw public key verification failed by calling SSL_get_verify_result(), and those that do, and take appropriate action, are not affected. This issue was introduced in the initial implementation of RPK support in OpenSSL 3.2. The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

Summary

openssl vulnerabilities

Details

It was discovered that OpenSSL clients incorrectly handled authenticating servers using RFC7250 Raw Public Keys. In certain cases, the connection will not abort as expected, possibly causing the communication to be intercepted. (CVE-2024-12797)

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)

A remote\nattacker could possibly use this issue to recover private data.\n(CVE-2024-13176)\n\nIt was discovered that OpenSSL incorrectly handled certain memory\noperations when using low-level GF(2^m) elliptic curve APIs with untrusted\nexplicit values for the field polynomial. When being used in this uncommon\nfashion, a remote attacker could use this issue to cause OpenSSL to crash,\nresulting in a denial of service, or possibly execute arbitrary code.\n(CVE-2024-9143)\n",
