OpenJPH through 0.32.0 contains a heap out-of-bounds write vulnerability in the HTJ2K cleanup-pass decoder that allows attackers to corrupt memory via one-row codeblocks. Attackers can supply a crafted .j2c or .jph codestream with small precinct sizes, causing the decoder to write a second row past the codeblock buffer, resulting in memory corruption and crashes.
