Yellow Dog Linux Security Announcement
--------------------------------------
Package: LPRng
Issue Date: July 25, 2001
Priority: high
Advisory ID: YDU-20010725-7
1. Topic:
LPRng has a group membership-related security problem.
2. Problem:
"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."
(from Red Hat's security advisory)
3. Solution:
a) Updating via yup...
We suggest that you use the Yellow Dog Update Program (yup)
to keep your system up-to-date. The following command(s) will
automatically retrieve and install the fixed version of
this update onto your system:
yup update LPRng
b) Updating manually...
The update can also be retrieved manually from our ftp site
below along with the rpm command that should be used to install
the update. (Please use a mirror site)
ftp://ftp.yellowdoglinux.com/pub/yellowdog/updates/yellowdog-2.0/ppc/RPMS/
rpm -Fvh LPRng-3.7.4-23b.ppc.rpm
4. Verification
MD5 checksum Package

If you wish to verify that each package has not been corrupted or tampered with,
examine the md5sum with the following command: rpm --checksig --nogpg filename
5. Misc.
Terra Soft has setup a moderated mailing list where these security, bugfix, and package
enhancement announcements will be posted. See http://lists.yellowdoglinux.com/ for more
