AI risk analysis

Summary: The flaw involves an integer overflow in the parsing of W64 CUE chunk metadata, leading to potential buffer overflows and code execution.
Exploitability: Exploitation is moderately difficult requiring a 32-bit build environment and specific input to trigger the overflow.
Blast radius: If exploited, this could lead to remote code execution, allowing attackers to gain full control over affected systems.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Disable the affected feature or upgrade to the latest version of dr_libs and dr_wav.h.

NVD description

dr_libs dr_wav.h (all versions through current master) contains an integer overflow in W64 CUE chunk metadata parsing. In drwav__metadata_process_chunk, a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to size_t before dividing by DRWAV_CUE_POINT_BYTES; on 32-bit builds this truncation causes the pre-allocated extra metadata capacity to be computed incorrectly.
