Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Andreas got some errata tool package check warnings today when he was updating cifs-utils in the RHEL5 samba3x package:
07:14 <@asn> BAD samba3x-client File /sbin/mount.cifs lost GNU_RELRO security protection on i386 x86_64 ppc ppc64 s390 s390x
07:14 <@asn> BAD samba3x-client PIE regression for file sbin/mount.cifs on all architectures
07:14 <@asn> BAD samba3x-client File /usr/sbin/cifs.upcall lost GNU_RELRO security protection on i386 x86_64 ppc ppc64 s390 s390x
07:14 <@asn> BAD samba3x-client PIE regression for file usr/sbin/cifs.upcall on all architectures
It looks like we're not taking advantage of all of the handy compiler/linker features to make these binaries as safe as possible. In particular, we ought to enable PIE and RELRO support in them.
I've sent a patch upstream to add support for this there and we ought to pull this into RHEL6 as well. Note that we don't have any reason to believe that there is any specific vulnerability here, but it's sensible to enable these proactively.
