Vulnerability from osv_openeuler – Published: 2024-04-12 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

LibRaw security update

Details

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):

Buffer Overflow vulnerability in LibRaw linux/unix v0.20.0 allows attacker to escalate privileges via the LibRaw_buffer_datastream::gets(char*, int) in /src/libraw/src/libraw_datastream.cpp.(CVE-2021-32142)

Severity

7.8 (High)
