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.
AnalysisAI
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. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. 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. Affected products include: Libraw.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
