SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA vulnerability has been found and corrected in cpio and tar :
Heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c in the rmt client functionality in GNU tar before 1.23 and GNU cpio before 2.11 allows remote rmt servers to cause a denial of service (memory corruption) or possibly execute arbitrary code by sending more data than was requested, related to archive filenames that contain a : (colon) character (CVE-2010-0624).
