BusyBox man Section Name Handling NULL Pointer Dereference Local DoS
BusyBox [1.33.0, 1.33.1], fixed in 1.34.0
The BusyBox toolkit implements a large number of Linux tools in a single executable and can even replace the Linux init system. Its small size and flexibility make it popular in embedded devices.
A NULL pointer dereference was found in the
man applet, which leads to denial of service when a section name is supplied but no page argument is given.
An attacker that controls
man command line arguments can trigger this issue.
