CVE-2026-24450

An integer overflow vulnerability exists in the uncompressed_fp_dng_load_raw functionality of LibRaw Commit 8dc68e2. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.

An integer overflow vulnerability exists in the uncompressed_fp_dng_load_raw functionality of LibRaw Commit 8dc68e2. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.

LibRaw is a library for reading RAW files from digital photo cameras (CRW/CR2, NEF, RAF, etc, virtually all RAW formats are supported).It pays special attention to correct retrieval of data required for subsequent RAW conversion.The library is intended for embedding in RAW converters, data analyzers, and other programs using RAW files as the initial data.

Security Fix(es):

An integer overflow vulnerability exists in the deflate_dng_load_raw functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.(CVE-2026-20884)

A heap-based buffer overflow vulnerability exists in the x3f_thumb_loader functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.(CVE-2026-20889)

A heap-based buffer overflow vulnerability exists in the HuffTable::initval functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow, causing memory corruption. This vulnerability affects specific commit versions.(CVE-2026-20911)

A heap-based buffer overflow vulnerability exists in the lossless_jpeg_load_raw functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.(CVE-2026-21413)

An integer overflow vulnerability exists in the uncompressed_fp_dng_load_raw functionality of LibRaw Commit 8dc68e2. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.(CVE-2026-24450)

A heap-based buffer overflow vulnerability exists in the x3f_load_huffman functionality of LibRaw. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.(CVE-2026-24660)

A flaw has been found in LibRaw up to 0.22.0. This affects the function LibRaw::nikon_load_padded_packed_raw of the file src/decoders/decoders_libraw.cpp of the component TIFF/NEF. Executing a manipulation of the argument load_flags/raw_width can lead to out-of-bounds read. It is possible to launch the attack remotely. The exploit has been published and may be used. Upgrading to version 0.22.1 mitigates this issue. This patch is called b8397cd45657b84e88bd1202528d1764265f185c. It is advisable to upgrade the affected component.(CVE-2026-5342)
