Ubuntu Security Notice USN-3817-1
November 13, 2018

python2.7, python3.4, python3.5 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Python.

Software Description:
- - python2.7: An interactive high-level object-oriented language
- - python3.5: An interactive high-level object-oriented language
- - python3.4: An interactive high-level object-oriented language

Details:

It was discovered that Python incorrectly handled large amounts of data. A
remote attacker could use this issue to cause Python to crash, resulting in
a denial of service, or possibly execute arbitrary code. This issue only
affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2018-1000030)

It was discovered that Python incorrectly handled running external commands
in the shutil module. A remote attacker could use this issue to cause
Python to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2018-1000802)

It was discovered that Python incorrectly used regular expressions
vulnerable to catastrophic backtracking. A remote attacker could possibly
use this issue to cause a denial of service. This issue only affected
Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2018-1060, CVE-2018-1061)

It was discovered that Python failed to initialize Expat's hash salt. A
remote attacker could possibly use this issue to cause hash collisions,
leading to a denial of service. (CVE-2018-14647)

Update instructions:

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

Ubuntu 18.04 LTS:
  python2.7                       2.7.15~rc1-1ubuntu0.1
  python2.7-minimal               2.7.15~rc1-1ubuntu0.1

Ubuntu 16.04 LTS:
  python2.7                       2.7.12-1ubuntu0~16.04.4
  python2.7-minimal               2.7.12-1ubuntu0~16.04.4
  python3.5                       3.5.2-2ubuntu0~16.04.5
  python3.5-minimal               3.5.2-2ubuntu0~16.04.5

Ubuntu 14.04 LTS:
  python2.7                       2.7.6-8ubuntu0.5
  python2.7-minimal               2.7.6-8ubuntu0.5
  python3.4                       3.4.3-1ubuntu1~14.04.7
  python3.4-minimal               3.4.3-1ubuntu1~14.04.7
