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...

Opera: RSA signature forgery

Background Opera is a multi-platform web browser. Description Opera makes use of OpenSSL, which fails to correctly verify PKCS 1 v1.5 RSA signatures signed by a key with exponent 3. Some CAs in Opera's list of trusted signers are using root certificates with exponent 3. Impact An attacker could...
