The Security Framework in Apple Mac OS X 10.4 through 10.4.8 allows remote attackers to cause a denial of service (resource consumption) via certain public key values in an X.509 certificate that requires extra resources during signature verification. NOTE: this issue may be similar to CVE-2006-2940.

Intoto iGateway VPN and iGateway SSL-VPN allow context-dependent 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 signature verification, a related issue to 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 signature verification.
