Package        : fsp
Vulnerability  : buffer overflow, directory traversal
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-1022 CAN-2004-0011

A vulnerability was discovered in fsp whereby a remote user could both
escape from the FSP root directory (CAN-2003-1022), and also overflow
a fixed-length buffer to execute arbitrary code (CAN-2004-0011).

For the current stable distribution (woody) this problem has been
fixed in version 2.81.b3-3.1woody1.

For the unstable distribution, this problem is fixed in version
2.81.b18-1.

We recommend that you update your fsp package.
