Title: Multiple Vendor Autofsd Vulnerability
Severity: CRITICAL
Description:
Autofsd is an RPC server which answers file system mount requests from the autofs file system. A vulnerability exists in the way autofsd processes map names when it receives a map request for an executable. Upon determining a file is executable, the server appends the client key and attempts to execute it. By sending a map name that is executable on the server (ie, any executable binary) and a key beginning with a semicolon or newline, followed by the commands to execute, arbitrary users can execute commands on the filesystem. Both IRIX 6.x and AIX 4.3 are vulnerable.
Affected Products:
- IBM AIX 4.3.0
- SGI IRIX 6.2.0
- SGI IRIX 6.3.0
- SGI IRIX 6.4.0
- SGI IRIX 6.5.0
- SGI IRIX 6.5.1
