Integer overflow in the RPC library in Libinfo in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to execute arbitrary code via crafted requests to portmap.

The Login Window in Apple Mac OS X 10.3.9 through 10.4.9 does not properly check certain environment variables, which allows local users to gain privileges via unspecified vectors.

The Login Window in Apple Mac OS X 10.4 through 10.4.9 does not display the screen saver authentication dialog in certain circumstances when waking from sleep, even though the "require a password to wake the computer from sleep" option is enabled, which allows local users to bypass authentication controls.

Use-after-free vulnerability in Libinfo in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors involving crafted web pages that trigger certain error conditions that are not properly reported in certain circumstances, resulting in accessing deallocated memory.

SMB in Apple Mac OS X 10.3.9 through 10.4.9 does not properly clean the environment when executing commands, which allows local users to gain privileges by setting unspecified environment variables.

The Login Window in Apple Mac OS X 10.4 through 10.4.9 displays the software update window beneath the loginwindow authentication dialog in certain circumstances related to running scheduled tasks, which allows local users to bypass authentication controls.

load_webdav in Apple Mac OS X 10.3.9 through 10.4.9 does not properly clean the environment when mounting a WebDAV filesystem, which allows local users to gain privileges by setting unspecified environment variables.

Buffer overflow in natd in network_cmds in Apple Mac OS X 10.3.9 through 10.4.9, when Internet Sharing is enabled, allows remote attackers to execute arbitrary code via malformed RTSP packets.

URLMount in Apple Mac OS X 10.3.9 through 10.4.9 passes the username and password credentials for mounting filesystems on SMB servers as command line arguments to the mount_sub command, which may allow local users to obtain sensitive information by listing the process.

Heap-based buffer overflow in the VideoConference framework in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to execute arbitrary code via a "crafted SIP packet when initializing an audio/video conference".
