USN-4151-2: Python vulnerabilities

Releases

• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• python2.7 - An interactive high-level object-oriented language
• python3.4 - An interactive high-level object-oriented language

Details

USN-4151-1 fixed several vulnerabilities in Python. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

It was discovered that Python incorrectly parsed certain email addresses. A
remote attacker could possibly use this issue to trick Python applications
into accepting email addresses that should be denied. (CVE-2019-16056)

It was discovered that the Python documentation XML-RPC server incorrectly
handled certain fields. A remote attacker could use this issue to execute a
cross-site scripting (XSS) attack. (CVE-2019-16935)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

• python3.4-minimal - 3.4.3-1ubuntu1~14.04.7+esm4
• python2.7 - 2.7.6-8ubuntu0.6+esm3
• python3.4 - 3.4.3-1ubuntu1~14.04.7+esm4
• python2.7-minimal - 2.7.6-8ubuntu0.6+esm3

Ubuntu 12.04

• python2.7 - 2.7.3-0ubuntu3.15
• python2.7-minimal - 2.7.3-0ubuntu3.15

In general, a standard system update will make all the necessary changes.
