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 < 2.03-r3 >= 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 ">=media-gfx/fbida-2.03-r3"
References ==========
