                      iTunes MPEG4 Parsing Buffer Overflow
                    [Apple iTunes 4.8 Security Enhancements]

May 10, 2005 18:00 GMT                                            Number P-201
______________________________________________________________________________
PROBLEM:       A security vulnerability was discovered in Apple iTunes 
               versions prior to 4.8. Updates for iTunes, a popular music 
               player, are available for Mac OS X, and Microsoft Windows 2000 
               and XP. 
PLATFORM:      Apple iTunes versions prior to 4.8 
DAMAGE:        A buffer overflow was found in the MPEG4 parsing code that has 
               the potential to cause a denial of service and possibly lead to 
               execution of arbitrary code. 
SOLUTION:      Apply available security updates. 
______________________________________________________________________________
VULNERABILITY  The risk is LOW. An attacker could craft a malicious MPEG4 file 
ASSESSMENT:    and convince a victim to load it and this may result in 
               execution of arbitrary code.
