A code issue vulnerability exists in Busybox, a set of applications containing several linux commands and tools developed by Denis Vlasenko, a Ukrainian personal developer, which stems from the fact that the product’s man applet does not handle certain input data appropriately. An attacker could cause a denial of service by providing a section while not mentioning the page parameter causing a NULL pointer dereference.
