Secunia Advisory: SA33632
Release Date: 2009-01-22
Critical: Highly critical
Impact: System access
Where: From remote
Solution Status: Vendor Patch
Software: Apple QuickTime 7.x
Description:
Some vulnerabilities have been reported in Apple QuickTime, which can be exploited by malicious people to compromise a user's system.
1) A boundary error exists in the processing of RTSP URLs. This can be exploited to cause a heap-based buffer overflow when a specially crafted RTSP URL is accessed.
2) An error due to improper validation of transform matrix data exists when processing Track Header (THKD) atoms in QuickTime Virtual Reality (QTVR) movie files. This can be exploited to cause a heap-based buffer overflow via a specially crafted QTVR file.
3) An error in the processing of "nBlockAlign" values in the "_WAVEFORMATEX" structure of AVI headers can be exploited to cause a heap-based buffer overflow when a specially crafted AVI file is accessed.
4) A boundary error exists in the processing of MPEG-2 video files containing MP3 audio content, which can be exploited to cause a buffer overflow via a specially crafted movie file.
5) An unspecified error exists in the processing of H.263 encoded movie files, which can be exploited to cause a memory corruption when a specially crafted movie file is viewed.
6) A signedness error exists within the processing of the MDAT atom when handling Cinepak encoded movie files. This can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed.
7) An error exists within the function JPEG_DComponentDispatch() when processing the image width data in JPEG atoms embedded in STSD atoms. This can be exploited to cause a memory corruption when a specially crafted movie file is viewed.
Successful exploitation of these vulnerabilities may allow execution of arbitrary code.
Solution:
Update to version 7.6.
