An issue was discovered in mj2/opj_mj2_extract.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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
