Debian Security Advisory DSA 3750-1 (libphp-phpmailer - security update)

Published: 2017-01-05 07:49:04
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
libphp-phpmailer on Debian Linux

Technical Details:
Many PHP developers utilize email in their code. The only PHP function that supports this is the mail() function. However, it does not provide any assistance for making use of popular features such as HTML-based emails and attachments.

Recommendations:
For the stable distribution (jessie), this problem has been fixed in version 5.2.9+dfsg-2+deb8u2. For the unstable distribution (sid), this problem has been fixed in version 5.2.14+dfsg-2.1. We recommend that you upgrade your libphp-phpmailer Linux Distribution Packages.

Summary:
Dawid Golunski discovered that PHPMailer, a popular library to send email from PHP applications, allowed a remote attacker to execute code if they were able to provide a crafted Sender address. Note that for this issue also CVE-2016-10045 was assigned, which is a regression in the original patch proposed for CVE-2016-10033. Because the origial patch was not applied in Debian, Debian was not vulnerable to CVE-2016-10045.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
