"It has been discovered, that a vulnerability in php5, a server-side,
HTML-embedded scripting language, could lead to exhausted disk space
on the server. When using overly long filenames or field names, a
memory limit could be hit which results in stopping the upload but not
cleaning up behind.

Further the embedded version of 'file' is vulnerable to
CVE-2019-18218. As it can not be exploited the same in php5 as in
file, this issue is not handled as an own CVE but just as a bug, that
has been fixed here (restrict the number of CDF_VECTOR elements to
prevent a heap-based buffer overflow (4-byte out-of-bounds write)).

For Debian 8 'Jessie', this problem has been fixed in version
5.6.40+dfsg-0+deb8u12.

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.");
