Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference due to improper NULL pointer validation in the sixel_decode_raw and sixel_decode functions. An attacker can cause the process to crash by triggering a low-memory condition that leads to a failed allocation, resulting in a NULL pointer dereference.
