Descriptions

The host_reliable_addrinfo function in support/export/hostname.c in nfs-utils before 1.2.4 does not properly use DNS to verify access to NFS exports, which allows remote attackers to mount filesystems by establishing crafted DNS A and PTR records.

La funciĆ³n host_reliable_addrinfo en support/export/hostname.c en nfs-utils anterior a 1.2.4 no utiliza debidamente DNS para verificar el acceso a exportaciones NFS, lo que permite a atacantes remotos montar sistemas de ficheros mediante el establecimiento de registros DNS A y PTR manipulados.
