Drake Wilson reported that the hack-local-variables() function in GNU
|
||
|
|
Emacs 22 does not properly match assignments of local variables in a
|
||
|
|
file against a list of unsafe or risky variables, allowing to override
|
||
|
|
them (CVE-2007-5795). Andreas Schwab (SUSE) discovered a stack-based
|
||
|
|
buffer overflow in the format function when handling values with high
|
||
|
|
precision (CVE-2007-6109).

|
Remote attackers could entice a user to open a specially crafted file
|
||
|
|
in GNU Emacs, possibly leading to the execution of arbitrary Emacs Lisp
|
||
|
|
code (via CVE-2007-5795) or arbitrary code (via CVE-2007-6109) with the
|
||
|
|
privileges of the user running GNU Emacs.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
The first vulnerability can be worked around by setting the
|
||
|
|
"enable-local-variables" option to "nil", disabling the processing of
|
||
|
|
local variable lists. GNU Emacs prior to version 22 is not affected by
|
||
|
|
this vulnerability. There is no known workaround for the second
|
||
|
|
vulnerability at this time.
|
||
|
|
</p>
|
||
|
|
</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All GNU Emacs users should upgrade to the latest version:
|
||
|
|
</p>

<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=app-editors/emacs-22.1-r3"</code>
