Message #5 received at submit@bugs.debian.org (full text, mbox, reply):
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 Suspect this whole function is obsolete though :)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.

The following bug was recently filed against the emacs23 package, and
after some preliminary research, it appears that the security issues
mentioned may still apply to 24.3. (Though it looks like the relevant
tramp file may now be tramp-sh.el).

Thanks for the quick help. I should have a new emacs24 package shortly.
