CVE-2014-2903

CVE-2014-2903 affects CyaSSL (WolfSSL) and related builds; the root cause is that key usage extension checking in leaf certificates is not performed, allowing a remote attacker to spoof a server with a certificate not authorized for SSL/TLS handshakes. The connected records corroborate the issue ...

Off-by-one Write Vulnerability

WolfSSL, formerly known as cyassl, is vulnerable to an off-by-one write vulnerability. This vulnerability in the x509 certificate parsing allows attackers to use an x509 certificate to cause denial of service DoS conditions and possibly remote code execution through a single out of bounds overwri...

CVE-2016-7438

The CVE-2016-7438 entry concerns wolfSSL (formerly CyaSSL) and its C software implementation of ECC. Affected is wolfSSL versions before 3.9.10, where the ECC code enables local attackers to more easily discover RSA keys by exploiting cache-bank hit differences. The impact is local, with partial ...

CVE-2016-7439

CVE-2016-7439 affects the C RSA implementation in wolfSSL (formerly CyaSSL) prior to 3.9.10. The vulnerability allows a local attacker to obtain RSA keys by exploiting cache-bank hit differences, i.e., an information-disclosure issue. Affected products/versions are wolfSSL before 3.9.10; impact i...

CVE-2016-7440

The CVE-2016-7440 issue affects the wolfSSL (formerly CyaSSL) C library’s AES Encryption/Decryption implementation prior to 3.9.10. The vulnerability enables local users to potentially discover AES keys by exploiting cache-bank timing differences during AES operations. The available connected doc...

CVE-2015-7744

wolfSSL formerly CyaSSL before 3.6.8 does not properly handle faults associated with the Chinese Remainder Theorem CRT process when allowing ephemeral key exchange without low memory optimizations on a server, which makes it easier for remote attackers to obtain private RSA keys by capturing TLS...

CVE-2015-7744

CVE-2015-7744 affects wolfSSL (formerly CyaSSL) before 3.6.8. The flaw is in handling faults during the CRT-based RSA key exchange when performing ephemeral key exchange on servers with limited memory, enabling remote attackers to extract private RSA keys from TLS handshakes (Lenstra attack). Pub...

CVE-2015-6925

CVE-2015-6925 affects wolfSSL (formerly CyaSSL) prior to 3.6.8. A remote attacker can cause a denial of service by sending a crafted DTLS cookie in a ClientHello, leading to resource consumption or traffic amplification. Public postings and vendor advisories confirm the vulnerability exists in ol...
