Heap-based buffer overflow in the QuickTime VR extension 7.2.0.240 in QuickTime.qts in Apple QuickTime before 7.3 allows remote attackers to execute arbitrary code via a QTVR (QuickTime Virtual Reality) movie file containing a large size field in the atom header of a panorama sample atom.

Heap-based buffer overflow in the QuickTime VR extension 7.2.0.240 in QuickTime.qts in Apple QuickTime before 7.3 allows remote attackers to execute arbitrary code via a QTVR (QuickTime Virtual Reality) movie file containing a large size field in the atom header of a panorama sample atom.

Heap-based buffer overflow in the QuickTime VR extension 7.2.0.240 in QuickTime.qts in Apple QuickTime before 7.3 allows remote attackers to execute arbitrary code via a QTVR (QuickTime Virtual Reality) movie file containing a large size field in the atom header of a panorama sample atom. Apple QuickTime is prone to a heap-based buffer-overflow issue because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue by enticing an unsuspecting user to open a specially crafted movie file. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the user running the application. Failed exploit attempts likely result in denial-of-service conditions. This issue affects Apple QuickTime running on Microsoft Windows Vista, Microsoft Windows XP SP2, and Mac OS X. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
