Apple posts security update for Mac Pro, Server 10.4.7

Apple has posted a security update for its new Mac Pro and Mac OS X Server v10.4.7.

The update is recommended for all Mac Pro systems running Mac OS X v10.4.7 (build 8K1079), and systems running Mac OS X Server v10.4.7 (Universal), according to Apple.

The security update improves the security of ImageIO and OpenSSH.

The fix to ImageIO prevents a problem that could cause an application to crash or arbitrary code to be executed when viewing a maliciously-crafted TIFF image. The update performs additional validation of TIFF images, according to Apple.

The OpenSSH fix prevents a denial of service when remote login is enabled and a nonexistent account causes the authentication process to hang. The update properly handles attempted logins by nonexistent users.
