An issue was discovered in OpenJPEG 2.3.0. Missing checks for headerinfo.height and headerinfo.width in the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow.
Out-of-bounds accesses in the functions pinextlrcp, pinextrlcp, pinextrpcl, pinextpcrl, pinextrpcl, and pinextcprl in openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).
