Mandrake Linux Security Advisory : tcltk (MDKSA-2002:060)
High Nessus Plugin ID 13961
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionSome problems were discovered with the Tcl/Tk development environment.
The expect application would search for its libraries in /var/tmp prior to searching in other directories, which could allow a local user to gain root privilege by writing a trojan library and waiting for the root user to run the mkpasswd utility. This is fixed in version 5.32 of expect. A similiar vulnerability has been fixed in the tcltk package which searched for its libraries in the current working directory prior to searching in other directories. This could be used to execute arbitrary code by local users through the use of a trojan library.
SolutionUpdate the affected packages.
