An issue was discovered in OpenJPEG 2.3.0. It allows remote attackers to cause a denial of service (attempted excessive memory allocation) in opjcalloc in openjp2/opjmalloc.c, when called from opjtcdinittile in openjp2/tcd.c, as demonstrated by the 64-bit opjdecompress.

An improper computation of ptx0, ptx1, pty0 and pty1 in the function opjgetencodingparameters in openjp2/pi.c in OpenJPEG through 2.3.0 can lead to an integer overflow.

Division-by-zero vulnerabilities in the functions pinextpcrl, pinextcprl, and pinextrpcl in openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).

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).

An issue was discovered in OpenJPEG 2.3.0. A heap-based buffer overflow was discovered in the function t2encodepacket in lib/openmj2/t2.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly unspecified other impact.
