Secunia Research reports :
CVE-2018-5800: An off-by-one error within the ‘LibRaw::kodak_ycbcr_load_raw()’ function (internal/dcraw_common.cpp) can be exploited to cause a heap-based buffer overflow and subsequently cause a crash.
CVE-2017-5801: An error within the ‘LibRaw::unpack()’ function (src/libraw_cxx.cpp) can be exploited to trigger a NULL pointer dereference.
CVE-2017-5802: An error within the ‘kodak_radc_load_raw()’ function (internal/dcraw_common.cpp) related to the ‘buf’ variable can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash.
