Description Dhananjay Arunesh 2019-07-23 06:05:08 UTC 
In OpenJPEG 2.3.1, there is excessive iteration in the opj_t1_encode_cblks
function of openjp2/t1.c. Remote attackers could leverage this vulnerability to
cause a denial of service via a crafted bmp file. This issue is similar to
CVE-2018-6616.
