Title: GnoRPM Arbitrary File Overwrite Vulnerability
Severity: LOW
Description:
A vulnerability exists in versions prior to v0.95 of GnoRPM, the Gnome graphical RPM manager, involving the way gnomerpm handles tmp files. GnomeRPM creates temporary files in the world-writeable /tmp directory with preditable filenames. It is possible for a malicious user to create symbolic links in /tmp with guessed/predicted filenames, knowing in advance that GnomeRPM will be run by root. When this happens, the files pointed to by the correctly guessed symbolic links will be overwritten by GnomeRPM (as root).
This can lead to a local denial of service if critical files are overwritten.
