CVE-2017-14164: Uclouvain Openjpeg

High severity, CVSS 8.8. EPSS: 5.4% chance of exploitation in the next 30 days.

A size-validation issue was discovered in opj_j2k_write_sot in lib/openjp2/j2k.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_write_bytes_LE in lib/openjp2/cio.c) or possibly remote code execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-14152.
