4) Description of Vulnerability
Secunia Research has discovered some vulnerabilities in libmikmod,
which can be exploited by malicious people to potentially compromise a
user's system.
1) Three boundary errors in the Impulse Tracker parser when parsing
an instrument containing a column, panning, or pitch envelope with
more than ENVPOINTS (32) points can result in a heap-based buffer
overflow.
2) A boundary error in the Ultratracker parser when parsing a file
with more than UF_MAXCHAN (64) channels can result in a heap-based
buffer overflow.
Successful exploitation may allow arbitrary code execution in the
context of the process using the libmikmod library when opening a
specially crafted module file.
