Debian DLA-1641-1 : mxml security update

high Nessus Plugin ID 121397

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several stack exhaustion conditions were found in mxml that can easily crash when parsing xml files.

CVE-2016-4570

The mxmlDelete function in mxml-node.c allows remote attackers to cause a denial of service (stack consumption) via crafted xml file.

CVE-2016-4571

The mxml_write_node function in mxml-file.c allows remote attackers to cause a denial of service (stack consumption) via crafted xml file

CVE-2018-20004

A stack-based buffer overflow in mxml_write_node via vectors involving a double-precision floating point number.

For Debian 8 'Jessie', these problems have been fixed in version 2.6-2+deb8u1.

We recommend that you upgrade your mxml 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 libmxml-dev, and libmxml1 packages.
