Descriptions

The sandboxing code in libarchive 3.2.0 and earlier mishandles hardlink archive entries of non-zero data size, which might allow remote attackers to write to arbitrary files via a crafted archive file.

El código sandboxing en libarchive 3.2.0 y versiones anteriores no maneja adecuadamente entradas de archivo de vínculo físico de datos de tamaño distinto de cero, lo que podría permitir a atacantes remotos escribir a archivos arbitrarios a través de un archivo manipulado.

A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive.
