EulerOS 2.0 SP5 : libxml2 (EulerOS-SA-2019-1316)

Medium Nessus Plugin ID 124443

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libxml2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A null pointer dereference vulnerability exists in the xpath function of libxml2 when parsing invalid XPath expression. Applications processing untrusted XSL format inputs with the use of libxml2 library may be vulnerable to denial of service attack due to crash of the application.(CVE-2018-14404)

- The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file.(CVE-2017-18258)

- A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to crash.(CVE-2015-8035)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libxml2 packages.
