gPS is a graphical application to watch system processes. In release 1.1.0 of the gps package, several security vulnerabilities were fixed, as detailed in the changelog:
All of these problems affect Debian's gps package version 0.9.4-1 in Debian woody. Debian potato also contains a gps package (version 0.4.1-2), but it is not affected by these problems, as the relevant functionality is not implemented in that version.
For the stable distribution (woody) these problems have been fixed in version 0.9.4-1woody1.
The old stable distribution (potato) is not affected by these problems.
For the unstable distribution (sid) these problems are fixed in version 1.1.0-1.
We recommend that you update your gps package.
