Severity: HIGH
Description:
sastcpd is a "Job Spawner" included with the base installation of the SAS Software infrastructure. It is available for various platforms. This issue affects systems running the Unix, Linux, and Microsoft operating systems.
A problem with the software could make it possible for a local user to gain elevated privileges. The problem is the handling of long in command line arguments.
A problem has been discovered in the sastcpd program. sastcpd is a job spawning program included with the SAS Base product. By default, it is installed setuid root. When sastcpd is executed with a command line argument of 1200 characters, a buffer overflow occurs. This overflow can result in the overwriting of stack variables, including the return address, and the execution of arbitrary code. As the sastcpd program is installed setuid root, the code will be executed with administrative privileges.
This problem makes it possible for a local user to gain administrative access.
