Description Laura Pardo 2018-07-31 13:15:03 EDT

A flaw was found in LibRaw versions before 0.18.9. An error within the samsung_load_raw() function (internal/dcraw_common.cpp) can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash.

Upstream patch:
https://github.com/LibRaw/LibRaw/commit/c9d8143eba4ff397163665e2119c6c5d7db54c55

Comment 4 Riccardo Schirone 2018-08-08 09:48:37 EDT

In RHEL 7, the code in dcraw_common.cpp, generated from dcraw.cpp, does not contain the `samsung_load_raw` function and it does not support the TIFF tag 40976, related to Samsung.

Comment 5 Riccardo Schirone 2018-08-08 09:48:45 EDT

Statement:

This issue did not affect the versions of LibRaw as shipped with Red Hat Enterprise Linux 7 as they did not include the vulnerable code.
