"The remote Debian host is missing a security update.");

"php-pear in php5 contains CWE-502 (Deserialization of Untrusted Data)
and CWE-915 (Improperly Controlled Modification of
Dynamically-Determined Object Attributes) vulnerabilities in its
Archive_Tar class. When extract is called without a specific prefix
path, can trigger unserialization by crafting a tar file with
`phar://[path_to_malicious_phar_file]` as path. Object injection can
be used to trigger destruct in the loaded PHP classes, all with
possible remote code execution that can result in files being deleted
or possibly modified.

For Debian 8 'Jessie', this problem has been fixed in version
5.6.39+dfsg-0+deb8u2.

We recommend that you upgrade your php5 packages.

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.");
