GNU Emacs is a highly extensible and customizable text editor. |

Drake Wilson reported that the hack-local-variables() function in GNU |
| 48 |
Emacs 22 does not properly match assignments of local variables in a |
| 49 |
file against a list of unsafe or risky variables, allowing to override |
| 50 |
them (CVE-2007-5795). Andreas Schwab (SUSE) discovered a stack-based |
| 51 |
buffer overflow in the format function when handling values with high |
| 52 |
precision (CVE-2007-6109). |

<impact type="normal"> |
| 56 |
<p> |
| 57 |
Remote attackers could entice a user to open a specially crafted file |
| 58 |
in GNU Emacs, possibly leading to the execution of arbitrary Emacs Lisp |
| 59 |
code (via CVE-2007-5795) or arbitrary code (via CVE-2007-6109) with the |
| 60 |
privileges of the user running GNU Emacs. |
| 61 |
</p> |
| 62 |
</impact> |
| 63 |
<workaround> |
| 64 |
<p> |
| 65 |
The first vulnerability can be worked around by setting the |
| 66 |
"enable-local-variables" option to "nil", disabling the processing of |
| 67 |
local variable lists. GNU Emacs prior to version 22 is not affected by |
| 68 |
this vulnerability. There is no known workaround for the second |
| 69 |
vulnerability at this time. |
| 70 |
</p> |
| 71 |
</workaround> |
| 72 |
<resolution> |
| 73 |
<p> |
| 74 |
All GNU Emacs users should upgrade to the latest version: |
| 75 |
</p> |
| 76 |
<code> |
| 77 |
# emerge --sync |
| 78 |
# emerge --ask --oneshot --verbose ">=app-editors/emacs-22.1-r3"</code> |
| 79 |
