Microsoft Windows POSIX buffer overflow allows local attacker to gain privileges
| win-posix-bo (16590) |  High Risk |
Description:
Microsoft Windows could allow a local attacker to gain elevated privileges on the system, caused by a buffer overflow in the POSIX subsystem. POSIX is the Portable Operating System Interface for Unix standard used in Windows NT and Windows 2000. A local attacker with valid logon credentials could exploit this vulnerability by supplying a long message to a vulnerable parameter, which would overflow a buffer and allow the attacker to gain elevated privileges and gain complete control of the system.
Consequences:
Gain Privileges
Remedy:
Apply the appropriate patch for your system, as listed in the Microsoft Security Bulletin MS04-020. See References.
