The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.

Finder in Mac OS X 10.2.8 and earlier sets global read/write/execute permissions on directories when they are dragged (copied) from a mounted volume such as a disk image (DMG), which could cause the directories to have less restrictive permissions than intended.

A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.

The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c.

The screen saver in MacOS X allows users with physical access to cause the screen saver to crash and gain access to the underlying session via a large number of characters in the password field, possibly triggering a buffer overflow.
