tip is a utility included with Sun Microsystems Solaris Operating Environment. tip allows a user to establish a full duplex terminal connection with a remote host.
|
|
|
|
A problem with tip could lead to a buffer overflow. Due to the improper handling of environment variables by tip, it is possible to overflow a buffer in the program, and execute arbitrary code. The tip binary is suid uucp, and exploitation could lead to an euid of uucp.
|
|
|
|
Therefore, it is possible for a local user to execute arbitrary code, and gain an euid of uucp, with the potential of gaining privileges elevated to root.
