Synopsis
gtkdiskfree is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.Background
gtkdiskfree is a GTK-based GUI to show free disk space.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
app-admin/gtkdiskfree | < 1.9.3-r1 | >= 1.9.3-r1 | All supported architectures |
Description
Eric Romang discovered that gtkdiskfree insecurely creates a predictable temporary file to handle command output.
Impact
A local attacker could create a symbolic link in the temporary files directory, pointing to a valid file somewhere on the filesystem. When gtkdiskfree is executed, this would result in the file being overwritten with the rights of the user running the application.
Workaround
There is no known workaround at this time.
Resolution
All gtkdiskfree users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/gtkdiskfree-1.9.3-r1"
