Buffer Overflow vulnerability in LibRaw::stretch() function in libraw\src\postprocessing\aspect_ratio.cpp.

A flaw was found in LibRaw. A heap-buffer-overflow in raw2image_ex() caused by a maliciously crafted file may lead to an application crash.

Libraw before 0.20.1 has a stack buffer overflow via LibRaw::identify_process_dng_fields in identify.cpp.

A buffer overflow vulnerability in LibRaw version < 20.0 LibRaw::GetNormalizedModel in src/metadata/normalize_model.cpp may lead to context-dependent arbitrary code execution.

LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.

The phase_one_correct function in Libraw before 0.17.1 allows attackers to cause memory errors and possibly execute arbitrary code, related to memory object initialization.

Array index error in smal_decode_segment function in LibRaw before 0.17.1 allows context-dependent attackers to cause memory errors and possibly execute arbitrary code via vectors related to indexes.

An error within the "parse_sinar_ia()" function (internal/dcraw_common.cpp) within LibRaw versions prior to 0.19.1 can be exploited to exhaust available CPU resources.

An error within the "parse_rollei()" function (internal/dcraw_common.cpp) within LibRaw versions prior to 0.19.1 can be exploited to trigger an infinite loop.

A type confusion error within the "unpacked_load_raw()" function within LibRaw versions prior to 0.19.1 (internal/dcraw_common.cpp) can be exploited to trigger an infinite loop.

LibRaw::raw2image() in libraw_cxx.cpp has a heap-based buffer overflow.

LibRaw::copy_bayer in libraw_cxx.cpp in LibRaw 0.19.1 has a NULL pointer dereference.

LibRaw::raw2image in libraw_cxx.cpp in LibRaw 0.19.1 has a NULL pointer dereference.

An integer overflow error within the "identify()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.12 can be exploited to trigger a division by zero via specially crafted NOKIARAW file (Note: This vulnerability is caused due to an incomplete fix of CVE-2018-5804).

An integer overflow error within the "parse_qt()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.12 can be exploited to trigger an infinite loop via a specially crafted Apple QuickTime file.

An error within the "parse_minolta()" function (dcraw/dcraw.c) in LibRaw versions prior to 0.18.11 can be exploited to trigger an infinite loop via a specially crafted file.

An error within the "nikon_coolscan_load_raw()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.9 can be exploited to trigger a NULL pointer dereference.

An error within the "nikon_coolscan_load_raw()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.9 can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash.

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

An error within the "LibRaw::parse_exif()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.9 can be exploited to cause a stack-based buffer overflow and subsequently execute arbitrary code.
