Description Laura Pardo 2018-07-31 17:34:14 UTC

A flaw was found in LibRaw versions before 0.18.9. An error within the rollei_load_raw() function (internal/dcraw_common.cpp) can be exploited to cause a heap-based buffer overflow and subsequently cause a crash.

Comment 3 Riccardo Schirone 2018-08-08 15:05:58 UTC

Function rollei_load_raw() does not check whether the index used to access the raw_image array is in bounds, thus a crafted raw image could cause a heap-based buffer overflow, which could result in a crash or in other unspecified effects.

Comment 6 Debarshi Ray 2018-11-22 16:34:14 UTC

This was fixed in LibRaw-0.18.9 and LibRaw-0.19.0-Beta3.
