Descriptions

The function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack.

La función WavpackVerifySingleBlock en open_utils.c en libwavpack.a en WavPack hasta la versión 5.1.0 permite que los atacantes provoquen una denegación de servicio (lectura fuera de límites y cierre inesperado de la aplicación) mediante un archivo WavPack Lossless Audio manipulado, tal y como queda demostrado con wvunpack.

WavPack is a completely open audio compression format providing lossless, high-quality lossy, and a unique hybrid compression mode. Issues addressed include denial of service and out of bounds read vulnerabilities.
