This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.
Multiple vulnerabilities have been discovered in Winamp, which can be exploited by malicious people to compromise a user's system.
1) An integer overflow error in the in_avi.dll plugin when allocating memory using the number of streams header value can be exploited to cause a heap-based buffer overflow via a specially crafted AVI file.
2) An integer overflow error in the in_avi.dll plugin when allocating memory using the RIFF INFO chunk's size value can be exploited to cause a heap-based buffer overflow via a specially crafted AVI file.
3) An error in the in_mod.dll plugin when parsing the song message data within Impulse Tracker (IT) files can be exploited to cause a heap-based buffer overflow.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
The vulnerabilities are confirmed in version 5.622. Other versions may also be affected.
Update to version 5.623.
