Gdm; Rhsa-2009:1364: Low Security And Bug Fix Update - Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual

• Allocatable arrays, objects with assumed size, and pointers to objects can be now accessed from
GDB in the same manner that they are accessed from the program being debugged.

, ,
• Variables of type 'logical (kind=8)' can be now accessed from GDB.
• For external references, GCC does not produce DWARF debug information. As a result, GDB
could not access Thread Local Storage (TLS) variables from a local source file if those variables
were defined in a different source file. This made it possible for certain memory addresses to
become unaccessible to GDB. With this release, GDB can now process TLS variables using ELF
structures instead of DWARF; as such, GDB can now access TLS variables regardless of where
those variables were defined.
• Running gcore (or any 'attach' or 'detach' command sequence) on a multi-threaded process that
was halted with 'kill -STOP' could unexpectedly resume some of that process's threads. This
behavior was caused by a kernel bug (present in upstream version 2.6.29) that remained unfixed in
Red Hat Enterprise Linux 5 kernels to maintain backward compatibility. While this update does not
fix the kernel bug, it applies a GDB workaround that ensures threads from a halted multi-threaded
process do not unexpectedly resume.
This update also implements various parts of Fortran language support. With this implementation,
gfortran44 (not gfortran) is now used to compile Fortran programs. The gfortran44 compiler is provided
by the gcc44 update (included in this release as a Technology Preview).
GDB users are advised to apply this update.

1.64.1. RHSA-2009:1364: Low security and bug fix update

Updated gdm packages that fix a security issue and several bugs are now available for Red Hat
Enterprise Linux 5.
This update has been rated as having low security impact by the Red Hat Security Response Team.
The GNOME Display Manager (GDM) is a configurable re-implementation of XDM, the X Display
Manager. GDM allows you to log in to your system with the X Window System running, and supports
running several different X sessions on your local machine at the same time.
A flaw was found in the way the gdm package was built. The gdm package was missing TCP
wrappers support, which could result in an administrator believing they had access restrictions
enabled when they did not.
This update also fixes the following bugs:
• the GDM Reference Manual is now included with the gdm packages. The gdm-docs package
installs this document in HTML format in "/usr/share/doc/".
• GDM appeared in English on systems using Telugu (te_IN). With this update, GDM has been
localized in te_IN. (BZ#226931
