Comment 3 Todd Cullum 2020-09-24 20:49:23 UTC

Correction: affected version should say = 0.20.0.

The vulnerable code was first introduced to LibRaw in 0.20.0. See:

1. https://www.libraw.org/news/libraw-0-20-Release
2. https://github.com/LibRaw/LibRaw/commit/d1975cb0e055d2bfe58c9d845c9a3e57c346a2f9#diff-7ba01eaad8f8766e799b7d3b1fba5640

Comment 4 Todd Cullum 2020-09-24 21:36:42 UTC

Statement:

This flaw does not affect LibRaw as shipped with Red Hat Enterprise Linux 7 or 8 as the vulnerable code was introduced in a subsequent version of LibRaw.
