The Java interface to CoreAudio on Apple Mac OS X 10.3.9 and 10.4.10 does not properly check the bounds of heap read and write operations, which allows remote attackers to execute arbitrary code via a crafted applet.
Buffer overflow in the UPnP IGD (Internet Gateway Device Standardized Device Control Protocol) implementation in iChat on Apple Mac OS X 10.3.9 and 10.4.10 allows network-adjacent remote attackers to execute arbitrary code via a crafted packet.
The Java interface to CoreAudio on Apple Mac OS X 10.3.9 and 10.4.10 does not restrict object instantiation and manipulation to valid heap addresses, which allows remote attackers to execute arbitrary code via a crafted applet.
The Bonjour functionality in mDNSResponder, iChat 3.1.6, and InstantMessage framework 428 in Apple Mac OS X 10.4.8 does not check for duplicate entries when adding newly discovered available contacts, which allows remote attackers to cause a denial of service (disrupted communication) via a flood of duplicate presence.tcp mDNS queries.
