The Linux /proc filesystem is a virtual filesystem provided by the Linux Kernel as an interface to some process and system information and parameters.
|
|
|
|
Under certain circumstances, an access validation error may exist in the handling of process-specific 'mem' files. The problem occurs when a process re-opens the standard input stream for reading from it's associated 'mem' file prior to executing another program using the exec() family of functions.
|
|
|
|
This could have serious ramifications in some situations if an attacker were to reposition the read offset of the file to an arbitrary location prior to executing a setuid program that obtains data from stdin.
