Vulnerability details

The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in the JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h within DjVuLibre due to a missing zero-bytes check in libdjvu/GBitmap.h.
