TITLE

Apple QuickTime buffer overflow vulnerability

DESCRIPTION

Heap-based buffer overflow in Apple QuickTime before 7.3 allows remote attackers to execute arbitrary code via malformed elements when parsing (1) Poly type (0x0070 through 0x0074) and (2) PackBitsRgn field (0x0099) opcodes in a PICT image. Apple QuickTime contains a stack buffer overflow vulnerability. If exploited, this vulnerability may allow an attacker to execute code. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exist in the parsing of the PackBitsRgn field (Opcode 0x0099). Due to improper handling of a malformed element in the structure, heap corruption occurs. If properly constructed this can lead to code execution running under the credentials of the user. Apple QuickTime is prone to multiple heap-based buffer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit these issues by enticing an unsuspecting user to open a specially crafted PICT image file. Failed exploit attempts likely result in denial-of-service conditions. These issues affects Apple QuickTime running on Microsoft Windows Vista, Microsoft Windows XP SP2, and Mac OS X. Apple QuickTime is a popular multimedia player that supports a wide variety of media formats. would trigger this overflow, resulting in the execution of arbitrary instructions. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 National Cyber Alert System Technical Cyber Security Alert TA07-310A Apple QuickTime Updates for Multiple Vulnerabilities Original release date: November 06, 2007 Last revised: -- Source: US-CERT Systems Affected Vulnerabilities in Apple QuickTime affect * Apple Mac OS X * Microsoft Windows Overview Apple QuickTime contains multiple vulnerabilities.

These can be exploited by untrusted Java applets to disclose sensitive information or to execute arbitrary code with escalated privileges when a user visits a web page containing a malicious Java applet. 4) A boundary error exists in the processing of panorama sample atoms in QTVR (QuickTime Virtual Reality) movie files, which can be exploited to cause a heap-based buffer overflow when a user is enticed to open a specially crafted movie file. 7) An error in the parsing of CTAB atoms can be exploited to cause a heap-based buffer overflow when a user opens a specially crafted movie file containing an invalid color table.
