Comment 3 Andrej Nemec 2016-05-13 08:13:55 UTC

CVE assignment:

http://seclists.org/oss-sec/2016/q2/342

Note that the problematic "(OPJ_UINT32)-1) / l_data_size" was apparently introduced in a patch addressing out-of-bounds read (or heap-based buffer over-read) vulnerabilities. See the pdfium.googlesource.com reference in CVE-2014-7947. In other words, CVE-2016-4797 exists because of an incorrect fix for CVE-2014-7947.
