Description Adam Mariš 2015-09-15 16:04:03 UTC
Use-after-free vulnerability was found in j2k.c in opj_j2k_write_mco function.

'l_current_data' is set to 'p_j2k->m_specific_param.m_encoder.m_header_tile_data',
'p_j2k->m_specific_param.m_encoder.m_header_tile_data' is later used as arg of 'realloc' and can be freed depending on the length of 'l_mco_size',
'l_current_data' is later used and can point to a freed memory zone
