In OpenJPEG 2.3.0, a stack-based buffer overflow was discovered in the pgxtoimage function in jpwl/convert.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution.

In OpenJPEG 2.3.0, a stack-based buffer overflow was discovered in the pgxtovolume function in jp3d/convert.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution.

An issue was discovered in mj2/opjmj2extract.c in OpenJPEG 2.3.0. The output prefix was not checked for length, which could overflow a buffer, when providing a prefix with 50 or more characters on the command line.

Division-by-zero vulnerabilities in the functions pinextpcrl, pinextcprl, and pinextrpcl in lib/openjp3d/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).
