Description Sam Fowler 2018-07-31 04:56:34 UTC 
LibRaw versions prior to 0.18.12 are vulnerable to an integer overflow in the internal/dcraw_common.cpp:identify() function. An attacker could exploit this to cause an divide-by-zero and resultant denial of service via a specially crafted NOKIARAW file.

This vulnerability was caused by an incomplete fix to CVE-2018-5804.

I believed this was introduced via https://github.com/LibRaw/LibRaw/commit/d5715aa86a83c756e38fdbae0e034e5a07901d49

This is not in RHEL7.

Statement:

This issue did not affect the versions of LibRaw as shipped with Red Hat Enterprise Linux 7.
Comment 6 Debarshi Ray 2018-09-27 13:54:18 UTC 
This was fixed in LibRaw 0.19.0-Beta6 and 0.18.12.
