CVE

CVE-2006-4407


TITLE

OpenSSL SSLv2 client code fails to properly check for NULL

Trust: 0.8

sources: CERT/CC: VU#386964

DESCRIPTION

The Security Framework in Apple Mac OS X 10.3.x up to 10.3.9 does not properly prioritize encryption ciphers when negotiating the strongest shared cipher, which causes Secure Transport to user a weaker cipher that makes it easier for remote attackers to decrypt traffic. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. This vulnerability may allow traffic to be weakly encrypted. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. Attackers may exploit these issues to execute arbitrary code, trigger denial-of-service conditions, escalate privileges, overwrite files, and access potentially sensitive information. Both local and remote vulnerabilities are present. When making a connection, the best cipher supported by both parties should be used. Due to errors in the priority order of credentials, Secure Transport may use ciphers that do not provide encryption or authentication when better ciphers are available
