TITLE

Apple Mac OS X Vulnerabilities in which important information is obtained in the login window

DESCRIPTION

Login Window in Apple Mac OS X 10.7.3, when Legacy File Vault or networked home directories are enabled, does not properly restrict what is written to the system log for network logins, which allows local users to obtain sensitive information by reading the log. Apple Mac OS X is prone to a local security-bypass vulnerability. Attackers can exploit this issue to bypass certain security restrictions and obtain sensitive account information. 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. 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. By sending a maliciously crafted message, a remote attacker could cause the directory server to disclose memory from its address space, potentially revealing account credentials or other sensitive information. By sending a maliciously crafted packet, an unauthenticated remote attacker could cause a denial of service or arbitrary code execution with system privileges. Processing untrusted input with the Security framework could result in memory corruption. This issue does not affect 32-bit processes. 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. CVE-ID CVE-2012-0675 : Renaud Deraison of Tenable Network Security, Inc. CVE-ID CVE-2011-2895 : Tomas Hoger of Red Hat Note: Additionally, this update filters dynamic linker environment variables from a customized environment property list in the user's home directory, if present.
