Heap-based buffer overflow in the AppleTalk networking stack in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allows remote attackers to cause a denial of service (system crash) via a ZIP NOTIFY (aka ZIPOPNOTIFY) packet that overwrites a certain ifPort structure member.

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.

Off-by-one error in the fbrealpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.

Directory Service in Apple Mac OS X through 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted message.

Directory Services in Apple Mac OS X 10.0.2, 10.0.3, 10.2.8, 10.3.2 and Apple Mac OS X Server 10.2 through 10.3.2 accepts authentication server information from unknown LDAP or NetInfo sources as provided by a malicious DHCP server, which allows remote attackers to gain privileges.
