TITLE

Apple Mac OS X Vulnerability in obtaining important information in directory services

DESCRIPTION

The directory server in Directory Service in Apple Mac OS X 10.6.8 allows remote attackers to obtain sensitive information from process memory via a crafted message. Apple Mac OS X is prone to multiple information-disclosure vulnerabilities. Attackers can leverage these issues to gain access to sensitive information. Information obtained may aid in further attacks. Note: This issue was previously discussed in BID 53445 (Apple Mac OS X Security Update 2012-002 Multiple Security Vulnerabilities) but has been given its own record to better document it. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2012-05-09-1 OS X Lion v10.7.4 and Security Update 2012-002 OS X Lion v10.7.4 and Security Update 2012-002 is now available and addresses the following: Login Window Available for: OS X Lion v10.7.3, OS X Lion Server v10.7.3 Impact: Remote admins and persons with physical access to the system may obtain account information Description: 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. The sensitive information may persist in saved logs after installation of this update. See http://support.apple.com/kb/TS4272 for more information on how to securely remove any remaining records. This issue only affects systems running OS X Lion v10.7.3 with users of Legacy File Vault and/or networked home directories.

This issue is addressed by enabling empty fragments. CVE-ID CVE-2011-3389 : Apple curl Available for: OS X Lion v10.7 to v10.7.3, OS X Lion Server v10.7 to v10.7.3 Impact: Using curl or libcurl with a maliciously crafted URL may lead to protocol-specific data injection attacks Description: 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. This issue does not affect OS X Lion systems. The Directory Server is disabled by default in non-server installations of OS X. CVE-ID CVE-2012-0651 : Agustin Azubel HFS Available for: OS X Lion v10.7 to v10.7.3, OS X Lion Server v10.7 to v10.7.3 Impact: Mounting a maliciously crafted disk image may lead to a system shutdown or arbitrary code execution Description: An integer underflow existed in the handling of HFS catalog files.

This issue is addressed by updating libtiff to version 3.9.5. CVE-ID CVE-2011-1167 Kernel Available for: OS X Lion v10.7 to v10.7.3, OS X Lion Server v10.7 to v10.7.3 Impact: When FileVault is used, the disk may contain unencrypted user data Description: An issue in the kernel's handling of the sleep image used for hibernation left some data unencrypted on disk even when FileVault was enabled. This issue is addressed through improved handling of the sleep image, and by overwriting the existing sleep image when updating to OS X v10.7.4. This issue does not affect systems prior to OS X Lion. CVE-ID CVE-2011-3212 : Felix Groebert of Google Security Team libarchive Available for: Mac OS X 10.6.8, Mac OS X Server 10.6.8, OS X Lion v10.7 to v10.7.3, OS X Lion Server v10.7 to v10.7.3 Impact: Extracting a maliciously crafted archive may lead to an unexpected application termination or arbitrary code execution Description: Multiple buffer overflows existed in the handling of tar archives and iso9660 files.

CVE-ID CVE-2012-0662 : aazubel working with HP's Zero Day Initiative Time Machine Available for: OS X Lion v10.7 to v10.7.3, OS X Lion Server v10.7 to v10.7.3 Impact: A remote attacker may access a user's Time Machine backup credentials Description: The user may designate a Time Capsule or remote AFP volume attached to an AirPort Base Station to be used for Time Machine backups. Beginning with AirPort Base Station and Time Capsule Firmware Update 7.6, Time Capsules and Base Stations support a secure SRP-based authentication mechanism over AFP. However, Time Machine did not require that the SRP-based authentication mechanism was used for subsequent backup operations, even if Time Machine was initially configured or had ever contacted a Time Capsule or Base Station that supported it. An attacker who is able to spoof the remote volume could gain access to user's Time Capsule credentials, although not backup data, sent by the user's system. This issue is addressed by requiring use of the SRP-based authentication mechanism if the backup destination has ever supported it.

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. - -- Vendor Response: Apple has issued an update to correct this vulnerability.
