The remote host is missing an update to gridengine announced via advisory DSA 2472-1.

Dave Love discovered that users who are allowed to submit jobs to a Grid Engine installation can escalate their privileges to root because the environment is not properly sanitized before creating processes. For the stable distribution (squeeze), this problem has been fixed in version 6.2u5-1squeeze1. For the unstable distribution (sid), this problem has been fixed in version 6.2u5-6. We recommend that you upgrade your gridengine packages.
