Severity: Normal
Title: fbida: Insecure temporary file creation
Date: April 23, 2006
Bugs: #129470
ID: 200604-13
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
fbida is vulnerable to linking attacks, potentially allowing a local
user to overwrite arbitrary files.
Background
==========
fbida is a collection of image viewers and editors for the framebuffer
console and X11.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/fbida lt; 2.03-r3 gt;= 2.03-r3
Description
===========
Jan Braun has discovered that the "fbgs" script provided by fbida
insecurely creates temporary files in the "/var/tmp" directory.
Impact
======
A local attacker could create links in the temporary file directory,
pointing to a valid file somewhere on the filesystem. When an affected
script is called, this could result in the file being overwritten with
the rights of the user running the script.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All fbida users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=media-gfx/fbida-2.03-r3"
References
==========
