DESCRIPTION:
Secunia Research has discovered a vulnerability in Csound, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in the
pv_import utility within the "pv_import()" function
(util/pv_import.c) and can be exploited to cause a heap-based buffer
overflow.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into converting a specially crafted file.

The vulnerability is confirmed in version 5.16.6. Other versions may
also be affected.

SOLUTION:
Do not process files from untrusted sources.
