| CVE-2008-5077 | 0.00 | — | 0.05 | Jan 7, 2009 | OpenSSL 0.9.8i and earlier does not properly check the return value from the EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys. | |||
| CVE-2008-5410 | 0.00 | — | 0.03 | Dec 10, 2008 | The PK11_SESSION cache in the OpenSSL PKCS#11 engine in Sun Solaris 10 does not maintain reference counts for operations with asymmetric keys, which allows context-dependent attackers to cause a denial of service (failed cryptographic operations) via unspecified vectors, related… | |||
| CVE-2008-1678 | 0.00 | — | 0.05 | Jul 10, 2008 | Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP… | |||

| CVE-2008-1672 | 0.00 | — | 0.05 | May 29, 2008 | OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference. | |||
