Debian DLA-1490-1 : php5 security update

high Nessus Plugin ID 112229
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

Two vulnerabilities have been discovered in php5, a server-side, HTML-embedded scripting language. One (CVE-2018-14851) results in a potential denial of service (out-of-bounds read and application crash) via a crafted JPEG file. The other (CVE-2018-14883) is an Integer Overflow that leads to a heap-based buffer over-read.

Additionally, a previously introduced patch for CVE-2017-7272 was found to negatively affect existing PHP applications (#890266). As a result of the negative effects and the fact that the security team has marked the CVE in question as 'ignore,' the patch has been dropped.

For Debian 8 'Jessie', these problems have been fixed in version 5.6.37+dfsg-0+deb8u1.

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.
