OpenSSL version rollback vulnerability

Overview OpenSSL from OpenSSL Project contains a version rollback vulnerability. If a specific option is used on a server running OpenSSL, an attacker can force the client and the server to negotiate the SSL 2.0 protocol even if these parties both request TLS 1.0 protocol by crafting an attack on...

Debian OpenSSL Predictable PRNG Bruteforce SSH Exploit

Exploit for multiple platform in category remote exploits ====================================================== Debian OpenSSL Predictable PRNG Bruteforce SSH Exploit ====================================================== the debian openssl issue leads that there are only 65.536 possible ssh key...

OpenSSL 0.9.8c-1 < 0.9.8g-9 (Debian and Derivatives) - Predictable PRNG Brute Force SSH

the debian openssl issue leads that there are only 65.536 possible ssh keys generated, cause the only entropy is the pid of the process generating the key. This leads to that the following perl script can be used with the precalculated ssh keys to brute force the ssh login. It works if such a key...

openssl: SSL_get_shared_ciphers() off-by-one

Off-by-one error in the SSLgetsharedciphers function in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f, might allow remote attackers to execute arbitrary code via a crafted packet that triggers a one-byte buffer underflow. NOTE: this issue was introduced as a result of a fix for CVE-2006-3738...

SOL8106 - OpenSSL SSL_get_shared_ciphers vulnerability CVE-2007-5135

F5 Product Development has determined that the BIG-IP and Enterprise Manager products use a vulnerable version of OpenSSL; however, the vulnerable code is not used in either TMM or in Apache on the BIG-IP system. The vulnerability is considered to be a local vulnerability and cannot be exploited...

CVE-2006-2940

OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service CPU consumption via parasitic public keys with large 1 "public exponent" or 2 "public modulus" values in X.509 certificates that require extra time to process when using RSA...

CVE-2006-4339

OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS 1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying...
