Description Karel Klíč 2010-06-01 15:40:08 UTC
Created attachment 418690 [details]
Fix for "array subscript is above array bounds"

Description of problem:
Compiler warning:
serv_list.c: In function 'add_server':
serv_list.c:487: warning: array subscript is above array bounds

GCC is right in this case. The array is accessed wrongly when the ypbind client is attached to _MAXSERVER (=30) servers and receives request to add another server.

This flaw has been fixed in newer release of ypbind, and the fix is obvious.

Comment 2 RHEL Product and Program Management 2010-06-03 10:13:05 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 4 Karel Volný 2010-10-01 09:16:03 UTC
the patch applies cleanly:

+ echo 'Patch #11 (ypbind-mt-1.20.4-add-server.patch):'
Patch #11 (ypbind-mt-1.20.4-add-server.patch):
+ /bin/cat /builddir/build/SOURCES/ypbind-mt-1.20.4-add-server.patch
+ /usr/bin/patch -s -p1 -b --suffix .add-server --fuzz=0

and the build log does not contain the warning, as can be seen here:
http://download.devel.redhat.com/brewroot/packages/ypbind/1.20.4/29.el6/data/logs/i686/build.log

the older version has the warning, see for example here:
http://download.devel.redhat.com/brewroot/packages/ypbind/1.20.4/23.el6/data/logs/i686/build.log

Comment 5 releng-rhel@redhat.com 2010-11-10 22:00:19 UTC
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
