The new Mac OS X 10.2.8 update contains fixes for the following vulnerabilities:
OpenSSH: Mac OS X 10.2.8 contains the patches to address CVE CAN-2003-0693, CAN-2003-0695, and CAN-2003-0682. On Mac OS X versions prior to 10.2.8, the vulnerability is limited to a denial of service from the possibility of causing sshd to crash. Each login session has its own sshd, so established connections are preserved up to the point where system resources are exhausted by an attack.
To deliver the update in a rapid and reliable manner, only the patches for CVE IDs listed above were applied, and not the entire set of patches for OpenSSH 3.7.1. Thus, the OpenSSH version in Mac OS X 10.2.8, as obtained via the "ssh -V" command, is: OpenSSH_3.4p1+CAN-2003-0693, SSH protocols 1.5/2.0, OpenSSL 0x0090609f
Sendmail: Addresses CVE CAN-2003-0694 and CAN-2003-0681 to fix a buffer overflow in address parsing, as well as a potential buffer overflow in ruleset parsing.
fb_realpath(): Fixes CAN-2003-0466 which is an off-by-one error in the fb_realpath() function that may allow attackers to execute arbitrary code.
arplookup(): Fixes CAN-2003-0804. The arplookup() function caches ARP requests for routes on a local link. On a local subnet only, it is possible for an attacker to send a sufficient number of spoofed ARP requests which will exhaust kernel memory, leading to a denial of service.
