The remote host is affected by the vulnerability described in GLSA-200510-01 (gtkdiskfree: Insecure temporary file creation)
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.
