Synopsis |
16 |
======== |
17 |
|
18 |
A flaw in fvwm-menu-directory may permit a local attacker to execute |
19 |
arbitrary commands with the privileges of another user. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
fvwm is a highly configurable virtual window manager for X11 desktops. |
25 |
fvwm-menu-directory allows fvwm users to browse directories from within |
26 |
fvwm. |

Affected packages |

================= |

|

------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |

1 x11-wm/fvwm < 2.5.18-r1 >= 2.5.18-r1 |

Description |
37 |
=========== |
38 |
|
39 |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that |
40 |
fvwm-menu-directory does not sufficiently sanitise directory names |
41 |
prior to generating menus. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A local attacker who can convince an fvwm-menu-directory user to browse |
47 |
a directory they control could cause fvwm commands to be executed with |
48 |
the privileges of the fvwm user. Fvwm commands can be used to execute |
49 |
arbitrary shell commands. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All fvwm users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=x11-wm/fvwm-2.5.18-r1" |
63 |
