For more information: SA20971 SA21865 3) A boundary error in the ImageIO component when processing JPEG2000 images can be exploited to cause a buffer overflow and may allow execution of arbitrary code. 4) An error in the kernel's error handling mechanism known as Mach exception ports can be exploited by malicious, local users to execute arbitrary code in privileged applications. 5) An unchecked error condition in the LoginWindow component may result in Kerberos tickets being accessible to other local users after an unsuccessful attempt to log in. 6) Another error in the LoginWindow component during the handling of "Fast User Switching" may result in Kerberos tickets being accessible to other local users. 7) A logic error in the LoginWindow component may allow network accounts without GUIDs to bypass the LoginWindow service access controls. 8) An error makes it possible for an account to manage WebObjects applications after the "Admin" privileges have been revoked. 9) A memory corruption error in QuickDraw Manager when processing PICT images can potentially be exploited via a specially crafted PICT image to execute arbitrary code. 10) An error in SASL can be exploited by malicious people to cause a DoS (Denial of Service) against the IMAP service. 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. For more information: SA21271 12) An error in Workgroup Manager may result in accounts in a NetInfo parent to use crypt even though they appear to use ShadowHash passwords.
