EulerOS Virtualization 2.5.3 : python (EulerOS-SA-2019-1357)

high Nessus Plugin ID 124735

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by contructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM.(CVE-2018-14647)

- A null pointer dereference vulnerability was found in the certificate parsing code in Python. This causes a denial of service to applications when parsing specially crafted certificates. This vulnerability is unlikely to be triggered if application enables SSL/TLS certificate validation and accepts certificates only from trusted root certificate authorities.(CVE-2019-5010)

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 python packages.
