A mishandled zero case was discovered in opjj2ksetcinemaparameters 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 opjwritebytesLE in lib/openjp2/cio.c and opjj2kwritesot in lib/openjp2/j2k.c) or possibly remote code execution.

An off-by-one error was discovered in opjtcdcodeblockencallocatedata in lib/openjp2/tcd.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 opjmqcflush in lib/openjp2/mqc.c and opjt1encodecblk in lib/openjp2/t1.c) or possibly remote code execution.

An invalid write access was discovered in bin/jp2/convert.c in OpenJPEG 2.2.0, triggering a crash in the tgatoimage function. The vulnerability may lead to remote denial of service or possibly unspecified other impact.

A stack-based buffer overflow was discovered in the pgxtoimage function in bin/jp2/convert.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution.
