"Francisco Alonso of Red Hat Product Security found an issue in the
file utility: when checking ELF files, note headers are incorrectly
checked, thus potentially allowing attackers to cause a denial of
service (out-of-bounds read and application crash) by supplying a
specially crafted ELF file.

For the long-term stable distribution (squeeze-lts), this problem has
been fixed in version 5.04-5+squeeze8.

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."
