Description Sam Fowler 2018-07-31 00:56:34 EDT 
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.

Comment 4 Stefan Cornelius 2018-07-31 10:40:43 EDT 
I believed this was introduced via https://github.com/LibRaw/LibRaw/commit/d5715aa86a83c756e38fdbae0e034e5a07901d49

This is not in RHEL7.
Comment 5 Stefan Cornelius 2018-07-31 10:40:52 EDT 
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 09:54:18 EDT 
This was fixed in LibRaw 0.19.0-Beta6 and 0.18.12.
