Description


Apple has issued a security update for Mac OS X, which fixes multiple vulnerabilities.

1) Alias Manager does not display identically-named files contained in identically-named mounted disk images. This can be exploited by malicious people to execute a malicious application by tricking a user into mounting two identically-named disk images.

2) Some errors in BIND can be exploited by malicious people to cause a DoS (Denial of Service).

For more information:
SA21752
SA23904

3) An integer overflow error in CoreGraphics when processing a PDF file can be exploited by malicious people to execute arbitrary code.

This does not affect systems prior to Mac OS X v10.4.

4) An error in crontabs may cause a DoS when filesystems mounted in /tmp gets deleted when the daily cleanup script is executed.

5) An error within the APOP implementation of fetchmail may be exploited by malicious people to disclose a user's password.

7) An error in iChat's UPnP IGD (Internet Gateway Device Standardized Device Control Protocol) module can be exploited by malicious people to cause a buffer overflow by sending a specially crafted packet to the application.

8) An error in mDNSResponder's UPnP IGD (Internet Gateway Device Standardized Device Control Protocol) module can be exploited by malicious people to cause a buffer overflow by sending a specially crafted packet to the application.

This does not affect systems prior to Mac OS X v10.4.

9) Insufficient access validation in pppd when processing the "plugin" command line option can be exploited by malicious, local users to load arbitrary plugins and gain escalated privileges.

This does not affect systems prior to Mac OS X v10.4.
