Package: emacs23 Version: 23.4+1-4 Severity: important There are several tempfile-vulnerabilities present in the Emacs Lisp bundled and distributed with the emacs23 package.
Here are four brief pointers to unsafe code: lisp/gnus/gnus-fun.el: In the function `gnus-grab-cam-face` the file "/tmp/gnus.face.ppm" is used, blindly allowing the existing file to be truncated, and symlinks followed. lisp/emacs-lisp/find-gc.el: In the function `trace-call-tree` there are some horrific invocations of the csh, which manipulate the directory and symlinks beneath "/tmp/esrc". lisp/net/browse-url.el In the function `browse-url-mosaic` the file "/tmp/Mosaic.$PID" is blindly overwritten. Suspect this whole function is obsolete though :) lisp/net/tramp.el The function `tramp-uudecode`, a fallback if a real uudecoding binary is not present, blindly uses "/tmp/tramp.$PID", truncating and removing the file. I suspect that each should receive a CVE identifier. -- System Information: Debian Release: 7.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.12-0.bpo.1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF8, LC_CTYPE=en_US.UTF8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF8) Shell: /bin/sh linked to /bin/dash Versions of packages emacs23 depends on: ii emacs23-bin-common 23.4+1-4 ii gconf-service 3.2.5-1+build1 ii libasound2 1.0.25-4 ii libatk1.0-0 2.4.0-2 ii libc6 2.13-38+deb7u1 ii libcairo2 1.12.2-3 ii libdbus-1-3 1.6.8-1+deb7u1 ii libfontconfig1 2.9.0-7.1 ii libfreetype6 2.4.9-1.1 ii libgconf-2-4 3.2.5-1+build1 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libgif4 4.1.6-10 ii libglib2.0-0 2.33.12+really2.32.4-5 ii libgpm2 1.20.4-6 ii libgtk2.0-0 2.24.10-2 ii libice6 2:1.0.8-2 ii libjpeg8 8d-1 ii libm17n-0 1.6.3-2 ii libncurses5 5.9-10 ii libotf0 0.9.12-2 ii libpango1.0-0 1.30.0-1 ii libpng12-0 1.2.49-1 ii librsvg2-2 2.36.1-2 ii libsm6 2:1.2.1-2 ii libtiff4 3.9.6-11 ii libtinfo5 5.9-10 ii libx11-6 2:1.5.0-1+deb7u1 ii libxft2 2.3.1-1 ii libxpm4 1:3.5.10-1 ii libxrender1 1:0.9.7-1+deb7u1 ii zlib1g 1:1.2.7.dfsg-13 emacs23 recommends no packages.
