Hanterm is a replacement for xterm which includes Hangul support, used for Korean language systems.
|
|
|
|
A buffer overflow error exists in hanterm. If it is called locally with a maliciously constructed parameter, it is possible to overflow a buffer. This can result in the return address of a stack frame being overwritten, and lead to the execution of arbitrary code.
|
|
|
|
As hanterm runs suid root on some systems, exploitation of this vulnerability may result in a local root compromise.
