Apple Security Advisory 2012-05-09-1
Posted May 10, 2012
Authored by Apple | Site apple.com

Apple Security Advisory 2012-05-09-1 - OS X Lion v10.7.4 and Security Update 2012-002 is now available and addresses multiple security issues. An issue existed in the handling of network account logins. The login process recorded sensitive information in the system log, where other users of the system could read it. A temporary file race condition issue existed in blued's initialization routine. There are known attacks on the confidentiality of SSL 3.0 and TLS 1.0 when a cipher suite uses a block cipher in CBC mode. curl disabled the 'empty fragment' countermeasure which prevented these attacks. This issue is addressed by enabling empty fragments. A data injection issue existed in curl's handling of URLs. This issue is addressed through improved validation of URLs. This issue does not affect systems prior to OS X Lion. Various other vulnerabilities have been addressed.
