The remote Debian host is missing a security-related update.
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.
Upgrade the file packages. For the stable distribution (wheezy), this problem has been fixed in version 5.11-2+deb7u6. For the upcoming stable distribution (jessie), this problem will be fixed soon.
