Title: Berkeley Parallel Make Buffer Overflow Vulnerability
Severity: HIGH
Description:
Parallel Make (pmake) is a freely available version of the make program, originally distributed with Berkeley Unix. It is designed to execute Makefiles and build programs.
A problem with pmake could make it possible for a local user to gain elevated privileges. The problem is due to a buffer overflow vulnerability in the program.
pmake is not typically setuid root, although some Linux distributions default to installing it this way. When a Makefile is executed by pmake, certain user-defined variables can be set in the Makefile by the user. One such variable is the shell definition variable, or .SHELL. By supplying a string of greater than 512 characters in the check= field of the .SHELL variable, it is possible to overwrite the return address, and execute of arbitrary code with root privileges.
This vulnerability could lead to a local user gaining elevated privileges, including administrative access, and could result in further compromise of an affected system.
