RHBA-2011:0468 - Bug Fix Advisory

Topic

Updated emacs packages that fix various bugs are now available for Red Hat
Enterprise Linux 5.

Description

GNU Emacs is a powerful, customizable, self-documenting text editor. It provides
special code editing features, a scripting language (elisp), and the capability
to read email and news.

This update fixes the following bugs:

• Previously, the emacs and emacs-nox packages did not provide any convenient

way for other packages to specify a dependency that can be satisfied by either
of the emacs variants. This update changes the emacs and emacs-nox packages and
provides the common symbol "emacs(bin)". (BZ#466580)

• Previously, the emacs-nox program was compiled with variable argument function

calls, which caused the program to terminate because it violated stack
protection boundaries. This occurred, for example, when the user tried to kill a
buffer with modifications. This update changes the emacs-nox package to call the
variable argument functions without triggering the stack protection. This update
also enables the stack protection for the emacs package. (BZ#499035)

All users of emacs are advised to upgrade to these updated packages, which fix
these bugs.
