Description Guilherme de Almeida Suckevicz 2021-03-12 20:32:34 UTC 
In read_and_discard_scanlines of jdapistd.c, there is a possible null pointer exception due to a missing NULL check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is needed for exploitation.
