Descriptions

The compress_bidder_init function in archive_read_support_filter_compress.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted tar file, which triggers an invalid left shift.

La función compress_bidder_init en archive_read_support_filter_compress.c en libarchive en versiones anteriores a 3.2.0 permite a atacantes remotos provocar una denegación de servicio (caída) a través de un archivo tar manipulado, lo que desencadena un desplazamiento a la izquierda no válida.

Undefined behavior (invalid left shift) was discovered in libarchive, in how Compress streams are identified. This could cause certain files to be mistakenly identified as Compress archives and fail to read.
