Rating: Highly critical

 

Description:

Some vulnerabilities have been reported in Apple QuickTime, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, and compromise a user's system.

 

1) An error in the handling of image description atoms can be exploited to cause a memory corruption when a user is enticed to open a specially crafted movie file.

 

2) A boundary error in the handling of Sample Table Sample Descriptor (STSD) atoms can be exploited to cause a heap-based buffer overflow when a user opens a specially crafted movie file.

 

3) Multiple errors exist in QuickTime for Java. 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.

 

5) A boundary error in the processing of PICT image files can be exploited to cause a stack-based buffer overflow when a user opens a specially crafted PICT image file containing an invalid length for the "UncompressedQuickTimeData" opcode.

 

6) Errors exist in the parsing of Poly type opcodes (opcodes 0x0070-74) and the PackBitsRgn field (Opcode 0x0099) when processing PICT image files. These can be exploited to cause a heap corruption when a user opens a specially crafted PICT image 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.

 

Successful exploitation of these vulnerabilities allows execution of arbitrary code.

 

Solution:

Update to version 7.3.
