Apple iTunes before 8.0 on Mac OS X 10.4.11, when iTunes Music Sharing is enabled but blocked by the host-based firewall, presents misleading information about firewall security, which might allow remote attackers to leverage an exposure that would be absent if the administrator were given better information.
Apple iTunes before 10.5.1 does not properly verify the authenticity of updates, which allows man-in-the-middle attackers to execute arbitrary code via a Trojan horse update, as demonstrated by evilgrade and DNS cache poisoning.
Heap-based buffer overflow in Apple iTunes before 7.4 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via crafted album cover art in the covr atom of an MP4/AAC file.
Integer overflow in the AAC file parsing code in Apple iTunes before 6.0.5 on Mac OS X 10.2.8 or later, and Windows XP and 2000, allows remote user-assisted attackers to execute arbitrary code via an AAC (M4P, M4A, or M4B) file with a sample table size (STSZ) atom with a "malformed" sample_size_table value.
Integer overflow in Apple QuickTime Player 7.0.3 and 7.0.4 and iTunes 6.0.1 and 6.0.2 allows remote attackers to execute arbitrary code via a FlashPix (FPX) image that contains a field that specifies a large number of blocks.
Multiple heap-based buffer overflows in QuickTime.qts in Apple QuickTime Player 7.0.3 and iTunes 6.0.1 (3) and earlier allow remote attackers to cause a denial of service (crash) and execute arbitrary code via a .mov file with (1) a Movie Resource atom with a large size value, or (2) an stsd atom with a modified Sample Description Table size value, and possibly other vectors involving media files. NOTE: item 1 was originally identified by CVE-2005-4127 for a pre-patch announcement, and item 2 was originally identified by CVE-2005-4128 for a pre-patch announcement.
