A buffer overflow vulnerability in the shared X library may allows local users to obtain higher privileges. Any setuid applications linked against the library are possibly vulnerable. The vulnerability is in the handling of the '-bg' command line parameter.
|
|
|
|
|
|
Setuid root applications known to be vulnerable inclue xload, xmcd, xterm, and scoterm.
|
|
|
|
Setuid bin applications known to be vulnerable include scosession.
