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.

Red Hat Product Errata RHBA-2011:1551 0 normal SHIPPED_LIVE openssh bug fix and enhancement update 2011-12-06 00:39:25 UTC

Description Karel Klíč 2011-08-08 15:19:49 UTC 
A problem related to debuginfo was found in the openssh-5.3p1-52.el6_1.2 package. This issue might affect crash analysis done by Automatic Bug Reporting Tool and its retrace server, and also prevent proper debugging of crashes via GDB.

A debuginfo file for a binary is not present in the debuginfo package. This might be caused by:
 - binary being compiled without debugging information
 - debugging information being removed from the binary by a build script
 - rpmbuild failing to extract debugging information from a binary in a buildroot because of permissions (eg. suid binaries, binaries without executable flag set)

affected binary: /usr/libexec/openssh/gnome-ssh-askpass
affected package: openssh-askpass-5.3p1-52.el6_1.2.i686
binary doesn't contain debug sections (it was probably stripped)
affected binary file mode: 100755

This issue can be investigated by using eu-readelf tool from the elfutils package. Use `eu-readelf --notes /path/to/binary` to get build ID of a binary. Then check that the debuginfo package does not contain /usr/lib/debug/.build-id/<aa>/<bbbbbbbb>, where <aa> are the first two chars of the build ID, and <bbbbbbbb> is the rest of it. It should be a symlink pointing back to the binary.

(This bug was detected and filed by a script.)
Comment 2 Jan F. Chadima 2011-08-08 22:57:16 UTC 
can you look at openssh-5.8p2-19.fc17.src.rpm if there is the bug repaired?
Comment 3 Karel Klíč 2011-08-09 09:31:09 UTC 
The bug is not fixed there. gnome-ssh-askpass is stripped when installed. openssh.spec:

%if ! %{no_gnome_askpass}
install -s contrib/gnome-ssh-askpass $RPM_BUILD_ROOT%{_libexecdir}/openssh/gnome-ssh-askpass
%endif


That -s option (== --strip) shouldn't be there. Rpmbuild extracts debug sections from binaries in buildroot, so the binaries must be installed there without stripping the debug sections.
Comment 4 Jan F. Chadima 2011-08-09 13:29:32 UTC 
ok , can you test openssh-5.8p2-20.fc17
Comment 5 Karel Klíč 2011-08-09 15:42:38 UTC 
The issue is fixed in openssh-5.8p2-20.fc17.
