Description:
Mark Seaborn has reported a vulnerability in Plash, which can be exploited by malicious people to bypass certain security restrictions and gain escalated privileges.
The vulnerability is caused due to Plash not correctly restricting sandboxed processes from inserting characters to the terminal's file descriptor via the TIOCSTI ioctl(). If a shell runs on that terminal, a malicious sandboxed process can exploit this to execute arbitrary commands with the full privileges of the running shell.
The vulnerability is reported in Plash 1.17. Other versions may also be affected.
