Summary

A stack-based buffer over-read in the ParseRiffHeaderConfig function of cli/riff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service attack or possibly have unspecified other impact via a maliciously crafted RF64 file.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

The ParseDsdiffHeaderConfig function of the cli/dsdiff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service (heap-based buffer over-read) or possibly overwrite the heap via a maliciously crafted DSDIFF file. The ParseCaffHeaderConfig function of the cli/caff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service (global buffer over-read), or possibly trigger a buffer overflow or incorrect memory allocation, via a maliciously crafted CAF file. Thuan Pham reports : An issue was discovered in WavPack 5.1.0 and earlier. The WAV parser component contains a vulnerability that allows writing to memory because ParseRiffHeaderConfig in riff.c does not reject multiple format chunks. An issue was discovered in WavPack 5.1.0 and earlier. The W64 parser component contains a vulnerability that allows writing to memory because ParseWave64HeaderConfig in wave64.c does not reject multiple format chunks. An issue was discovered in WavPack 5.1.0 and earlier for WAV input. Out-of-bounds writes can occur because ParseRiffHeaderConfig in riff.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.
