Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the CONS_HISTORY ioctl handler. An attacker can cause a heap buffer overflow by supplying a large history size value, leading to an integer overflow in buffer size calculation and subsequent out-of-bounds write in kernel memory. This may allow privilege escalation by a local unprivileged user with access to a vt(4) device.
