libraw: code execution

From the Secunia advisory:

Two vulnerabilities have been reported in LibRaw, which can be exploited by malicious people to potentially compromise an application using the library.

1) A double-free error exits when handling damaged full-color within Foveon and sRAW files.

2) An error during exposure correction can be exploited to cause a buffer overflow.

Successful exploitation may allow execution of arbitrary code.
