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.
DirectoryServices in MacOS X trusts the PATH environment variable to locate and execute the touch command, which allows local users to execute arbitrary commands by modifying the PATH to point to a directory containing a malicious touch program.
Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string.
The Sun RPC functionality in multiple libc implementations does not provide a time-out mechanism when reading data from TCP connections, which allows remote attackers to cause a denial of service (hang).
