Description Agostino Sarubbo gentoo-dev 2012-04-04 19:04:19 UTC
From secunia security advisory at $URL:

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.

@security: This can probably be closed since it should be fixed in recent versions in the tree.
