Multiple vulnerabilities have been reported in QuickTime, which can be exploited by malicious people to compromise a user's system.

1) An integer overflow error within the processing of JPEG images can be exploited via a specially crafted JPEG image to crash the application and potentially execute arbitrary code.

2) An integer overflow and boundary error within the processing of QuickTime movies can be exploited via a specially crafted QuickTime movie to crash the application and potentially execute arbitrary code.

3) A boundary error within the processing of Flash movies can be exploited via a specially crafted Flash movie to crash the application and potentially execute arbitrary code.

4) An integer overflow and boundary error within the processing of H.264 movies can be exploited via a specially crafted H.264 movie to crash the application and potentially execute arbitrary code.

5) A boundary error within the processing of MPEG4 movies can be exploited via a specially crafted MPEG4 movie to crash the application and potentially execute arbitrary code.

6) An integer overflow error within the processing of FlashPix images (".fpx") can be exploited via a specially crafted FlashPix image with an overly large value in the field specifying the number of data blocks in the file. This can be exploited to cause a heap-based buffer overflow and allows execution of arbitrary code.

7) A boundary error within the processing of AVI movies can be exploited via a specially crafted AVI movie to crash the application and potentially execute arbitrary code.

8) Two boundary errors within the processing of PICT images can be exploited to either cause a stack-based buffer overflow via a PICT image with specially crafted font information or a heap-based buffer overflow via a PICT image with specially crafted image data. This can be exploited to crash the application and potentially execute arbitrary code.

9) A boundary error within the processing of BMP images can be exploited via a specially crafted BMP image to crash the application and potentially execute arbitrary code.
