An update of the python2 package has been released.

According to the version of the python packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - A security regression of CVE-2019-9636 was discovered     in python, since commit     d537ab0ff9767ef024f26246899728f0116b1ec3, which still     allows an attacker to exploit CVE-2019-9636 by abusing     the user and password parts of a URL. When an     application parses user-supplied URLs to store cookies,     authentication credentials, or other kind of     information, it is possible for an attacker to provide     specially crafted URLs to make the application locate     host-related information (e.g. cookies, authentication     data) and send them to a different host than where it     should, unlike if the URLs had been correctly parsed.
    The result of an attack may vary based on the     application.(CVE-2019-10160)

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.

Multiple vulnerabilities were discovered in Python2.7, an interactive high-level object-oriented language.

CVE-2018-20852

By using a malicious server an attacker might steal cookies that are meant for other domains.

CVE-2019-5010

NULL pointer dereference using a specially crafted X509 certificate.

CVE-2019-9636

Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization resulting in information disclosure (credentials, cookies, etc. that are cached against a given hostname).
A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.

CVE-2019-9740

An issue was discovered in urllib2 where CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the query string after a ? character) followed by an HTTP header or a Redis command.

CVE-2019-9947

An issue was discovered in urllib2 where CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character) followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue.

CVE-2019-9948

urllib supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file:
URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.

CVE-2019-10160

A security regression of CVE-2019-9636 was discovered which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed.
The result of an attack may vary based on the application.

CVE-2019-16056

The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied.

CVE-2019-20907

Opening a crafted tar file could result in an infinite loop due to missing header validation.

For Debian 9 stretch, these problems have been fixed in version 2.7.13-2+deb9u4.

We recommend that you upgrade your python2.7 packages.
