Zero Day Initiative Advisory 12-137

Zero Day Initiative Advisory 12-137 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Mac OSX. Authentication is not required to exploit this vulnerability. The flaw exists within the libsecurity_cdsa_plugin which implements routines defined in libsecurity_cssm. The library defines an allocation routine as having an argument type uint32. The implemented methods in the cdsa_plugin accept parameter having type size_t, this value is truncated from 64 bits to 32 bits when being passed to the library routine. This can lead to an underallocated memory region and ultimately a write out of bounds. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the process.

Apple Security Advisory 2012-05-09-1

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.
