CVE-2014-9653

readelf.c does not consider that pread calls sometimes read only a
subset of the available data, which allows remote attackers to cause a
denial of service (uninitialized memory access) or possibly have
unspecified other impact via a crafted ELF file.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
