Description:
Piotr Bania has discovered a vulnerability in Winamp, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error within the LIBSNDFILE.DLL library when handling Matlab version 4.2 files. This can be exploited to overwrite an arbitrary memory location with a NULL byte when opening a specially crafted MAT file.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in version 5.33. Other versions and applications that use the library may also be affected.
Solution:
Update to version 5.34 or later.
