GATOS xatitv exported_display() Local Overflow
Local Access Required Input Manipulation
Loss of Integrity
Exploit Unknown

- 漏洞描述

A local overflow exists in gatos xatitv. Xatitv contains a boundary error in the exported_display() function of xutils.c resulting in a buffer overflow. With a specially crafted request, an attacker can cause privilege escalation and arbitrary code execution resulting in a loss of integrity.

- 漏洞讨论

An unspecified buffer overflow vulnerability affects the gatos xatitv utility, which is setuid by default. This issue is due to a failure of the application to properly validate the length of user-supplied strings prior to copying them into static process buffers.

The details currently available surrounding this issue are insufficient to provide and accurate technical description. It is not known if this issue is triggered by an excessively long command line argument, or by some configuration file parameter, or by some multimedia file parameter.

This BID will be updated as more details are released.

An attacker may leverage this issue to execute arbitrary instructions with the privileges of the superuser. This may potentially lead to privilege escalation or unauthorized access.
