Debian DLA-2261-1 : php5 security update

medium Nessus Plugin ID 137886

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected packages.
