CVE-2017-14151
The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_mqc_flush in lib/openjp2/mqc.c and opj_t1_encode_cblk in lib/openjp2/t1.c) or possibly remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
