Debian alert: New XEmacs and gnuserv packages available
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ---------------------------------------------------------------------------- Debian Security Advisory DSA-042-1 security@debian.org http://www.debian.org/security/ Martin Schulze March 8, 2001 - ---------------------------------------------------------------------------- Packages : gnuserv, xemacs21 Vulnerability : buffer overflow and weak security Type : remote vulnerability Debian-specific: no Fixed version : gnuserv 2.1alpha-5.1 (potato) and 2.1alpha-5.1.1 (unstable) xemacs 21.1.10-5 (potato) and xemacs 21.1.14-1 (unstable) Klaus Frank has found a vulnerability in the way gnuserv handled remote connections. Gnuserv is a remote control facility for Emacsen which is available as standalone program as well as included in XEmacs21. Gnuserv has a buffer for which insufficient boundary checks were made. Unfortunately this buffer affected access control to gnuserv which is using a MIT-MAGIC-COOCKIE based system. It is possible to overflow the buffer containing the cookie and foozle cookie comparison. Gnuserv was derived from emacsserver which is part of GNU Emacs. It's was reworked completely and not much is to be left over from its time as part of GNU Emacs. Therefore the versions of emacssserver in both Emacs19 and Emacs20 doesn't look vulnerable to this bug, they don't even provide a MIT-MAGIC-COOKIE based mechanism. This could lead into a remote user issue commands under the UID of the person running gnuserv. We recommend you upgrade your xemacs21 and gnuserv packages immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. You may use an automated update by adding the resources from the footer to the proper configuration. Debian GNU/Linux 2.2 alias potato - ------------------------------------ Potato was released for the alpha, arm, i386, m68k, powerpc and sparc architectures.
