Description

Mail in Apple Mac OS X before 10.6.3 does not properly enforce the key usage extension during processing of a keychain that specifies multiple certificates for an e-mail recipient, which might make it easier for remote attackers to obtain sensitive information via a brute-force attack on a weakly encrypted e-mail message.

Affected products

macOS: through 10.6.2; 10.5.0, 10.5.1, 10.5.2, 10.5.3, 10.5.4, 10.5.5 (+5)
Apple Mac Os X Server: through 10.6.2; 10.5.0, 10.5.1, 10.5.2, 10.5.3, 10.5.4, 10.5.5 (+5)
