Description:
Some vulnerabilities have been reported in Winamp, which can be exploited by malicious people to compromise a user's system.
1) Multiple errors in the FLAC library can be exploited to cause heap-based or stack-based buffer overflows via specially-crafted FLAC media files.
For more information:
SA27210
The vulnerabilities are reported in version 5.35. Other versions may also be affected.
2) Multiple boundary errors in in_mp4.dll when processing certain MP4 atoms (aART, ©alb, ©ART, ©cmt, ©day, ©gen, ©nam, ©wrt) can be exploited to cause stack-based buffer overflows via a specially crafted MP4 file.
Successful exploitation allows execution of arbitrary code but requires that the user is tricked into opening a malicious MP4 file and clicking "Update" on the "File Info" window (Alt+3).
The vulnerabilities are confirmed in version 5.32, 5.33, 5.34, and 5.35. Other versions may also be affected.
Solution:
Update to version 5.5.
