curl: CVE-2025-4947: QUIC certificate check skip with wolfSSL

Summary: When using WolfSSL as the TLS backend, there is an issue where the CN or SAN in the certificate is not verified when connecting to an IP address over HTTP/3. wolfSSLX509checkhost is only called when peer-sni is not NULL. However, when an IP address is specified, peer-sni is NULL, so the...

SUSE CVE-2024-5288

An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSLCHECKSIGFAULTS is used in signing operations with private ECC keys, such as in server-side TLS connections, the connection is halted if any fault...

The vulnerability of the WOLFSSL_CHECKSIG_FAULTS configuration in the SSL/TLS WolfSSL library allows a perpetrator to gain unauthorized access to protected information. [source-iocs-preserved const=WOLFSSL_CHECK_SIG_FAULTS]

The vulnerability of the WOLFSSLCHECKSIGFAULTS configuration in the SSL/TLS library WolfSSL is related to improper verification of the ECDSA cryptographic signature. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information by performing a Rowhammer...
