CFNetwork
CVE-ID: CVE-2010-1800
Available for: Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: An attacker with a privileged network position may intercept user credentials or other sensitive information
Description: CFNetwork permits anonymous TLS/SSL connections. This may allow a man-in-the-middle attacker to redirect connections and intercept user credentials or other sensitive information. This issue does not affect the Mail application. This issue is addressed by disabling anonymous TLS/SSL connections. This issue does not affect systems prior to Mac OS X v10.6.3.

libsecurity
CVE-ID: CVE-2010-1802
Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8, Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: An attacker in a privileged network position who can obtain a domain name that differs only in the last characters from the name of a legitimate domain may impersonate hosts in that domain
Description: An issue exists in the handling of certificate host names. For host names containing three or more components, the last characters are not properly compared. In the case of a name containing exactly three components, only the last character is not checked. For example, if an attacker in a privileged network position could obtain a certificate for www.example.con the attacker can impersonate www.example.com. This issue is addressed through improved handling of certificate host names. Credit to Peter Speck for reporting this issue.
