Imlib2 is a freely available, open source graphics library available for the Linux and Unix operating systems. It is maintained by Michael Jennings.
|
|
|
|
Imlib2 is installed on many operating systems and linked with graphical programs such as Eterm. Some programs linked with the library are setuid, such as Eterm which is a setuid utmp program. In some cases, a buffer overflow in the $HOME environment variable may occurs, such as when the $HOME environment variable is filled with 4128 bytes and Eterm is executed. This can allow a local user to overwrite stack variables up through the return address, and execute arbitrary code. As the Eterm program is setgid utmp, this code would be executed with utmp privileges.
