#1 | Link | KMPlayer MP3 File Processing Buffer Overflow Vulnerability, Posted 06-08-2011
A vulnerability has been discovered in KMPlayer, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error when processing MP3 files
and can be exploited to cause a stack-based buffer overflow via a
specially crafted file.

Successful exploitation allows execution of arbitrary code, but
requires tricking a user into opening a malicious MP3 file.

The vulnerability is confirmed in version Other versions
may also be affected.

Do not open MP3 files from untrusted sources.

Thank you for reporting!

Although there's no description what's causing the overflow I'd recommend to change the splitter/source filter and the decoder for MP3.

This issue has not been confirmed official yet.

EDIT: Secunia reports: "Where: From remote", and the description "tricking a user into opening a malicious MP3 file"
Would be "local" for me. However KMPlayer handles MP3 radio streams so it seems obvious to me that those should not be used until this is fixed. If those work then it would be "remote".
Please read this before you post and use the Forums Search. Read other sticky threads, too. Thank you.
Impurities make things work and sometimes unique.

I fully agree with the HXD and add that, too, became ill RealMedia reproduce at these same files in 1440 are going well.
If you want to just kill KMPlayer you are right.
