Detail

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

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