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

1) Three boundary errors in the Module Decoder Plug-in (IN_MOD.DLL) when parsing instrument definitions can be exploited to cause heap-based buffer overflows via a specially crafted Impulse Tracker file.

2) A boundary error in the Module Decoder Plug-in when parsing samples can be exploited to cause a heap-based buffer overflow via a specially crafted Impulse Tracker file.

3) An error in the Module Decoder Plug-in when parsing Ultratracker files can be exploited to cause a heap-based buffer overflow.

4) An integer overflow error in the Module Decoder Plug-in when parsing Oktalyzer files can be exploited to cause a heap-based buffer overflow.

5) An integer overflow error when parsing PNG or JPEG data may result in memory corruption.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
