Synopsis:

LibRaw security updateSummary:

An update for LibRaw is now available for openEuler-20.03-LTS-SP4Description:

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)

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...
