Description

When LPRng drops uid and gid, it fails to drop membership in its supplemental groups.

LPRng fails to drop supplemental group membership at init time, though it does properly setuid and setgid. The result is that LPRng, and its children, maintain any supplemental groups that the process starting LPRng had at the time it started LPRng. This is a security risk.
