Description Pedro Sampaio 2018-09-06 14:44:28 UTC 
An issue was discovered in OpenJPEG 2.3.0. Missing checks for header_info.height and header_info.width in the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow.

Upstream bug:

Upstream issue: https://github.com/uclouvain/openjpeg/issues/861
Patch: https://github.com/uclouvain/openjpeg/commit/c22cbd8bdf8ff2ae372f94391a4be2d322b36b41

Analysis:
Heap-buffer overflow while converting image from PNM format. Specially-crafted values in the header, could cause integer overflow. This leads to a small buffer being allocated. Later when file contents are read into this buffer it leads to heap-overflow. Arbitrary code execution could be possible.
