SYSTEMS AFFECTED
SunOS 4.1.x
PROBLEM
An lpd bug was discovered where lpd could be used to remove
system files (/etc/passwd or /.rhosts as examples). This bug was
fixed with 100305-01.
A second bug was also shown that could still be used to remove
system files. This fix was rolled into 100305-02.
An lpc problem that touched one of the same modules as in the
lpd fix was fixed and the subsequent change rolled into the lpd
patch 100305-03.
Two additional problems were sent to Sun: one having to do with
RPC calls to lpd and the second having to do with postscript
calls to lpd, thus 100305-04.
It was in creating the -04 version that we unknowingly
introduced a remote spool problem on the SunOS 4.1.1 version of
the patch. The problem was that if the remote queue had jobs in
it, the local job sent was often truncated to zero length.
The -05 version was an attempt to back out the last few changes
to remove the remote print problem. Unfortunately, it did not.
It was at this time that we decided to do a lengthy evaluation
and test cycle to ensure that the newest version fixed all the
reported problems as well as fixed the remote spool bug we had
introduced.
The 100305-06 patch is the result of that lengthy test cycle.
