CVE-2006-4397

TITLE

Apple Workgroup Manager fails to properly enable ShadowHash passwords

DESCRIPTION

Unchecked error condition in LoginWindow in Apple Mac OS X 10.4 through 10.4.7 prevents Kerberos tickets from being destroyed if a user does not successfully log on to a network account from the login window, which might allow later users to gain access to the original user's Kerberos tickets. Apple Workgroup Manager fails to properly enable ShadowHash passwords in a NetInfo parent. Workgroup Manager may appear to use ShadowHash passwords when crypt is used. A vulnerability exists in how Apple OS X handles PICT images. If successfully exploited, this vulnerability may allow a remote attacker to execute arbitrary code, or create a denial-of-service condition. This vulnerability may allow remote users with a valid network account to bypass LoginWindow service access controls. Adobe Flash Player fails to properly handle malformed strings. These issue affect Mac OS X and various applications including CFNetwork, Safari, Kernel, ImageIO, LoginWindow, System Preferences, QuickDraw Manager, and Workgroup Manager. There is a vulnerability in the implementation of Kerberos that the error situation is not handled correctly. Impacts of other vulnerabilities include bypass of security restrictions and denial of service. I. Further details are available in the individual Vulnerability Notes for Apple Security Update 2006-006. More information on those vulnerabilities can be found in Adobe Security Bulletin APSB06-11 and the Vulnerability Notes for Adobe Security Bulletin APSB06-11. II. Impact The impacts of these vulnerabilities vary. For information about specific impacts, please see the Vulnerability Notes for Apple Security Update 2006-006. Potential consequences include remote execution of arbitrary code or commands, bypass of security restrictions, and denial of service. III. This and other updates are available via Apple Update or via Apple Downloads. IV.

For more information: SA19618 11) A memory management error in WebKit's handling of certain HTML can be exploited by malicious people to compromise a user's system.
