Ubuntu Security Notice USN-3813-1
November 08, 2018

pyopenssl vulnerabilities

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

- - Ubuntu 16.04 LTS


Several security issues were fixed in pyOpenSSL.

Software Description:
- - pyopenssl: Python wrapper around the OpenSSL library


It was discovered that pyOpenSSL incorrectly handled memory when handling
X509 objects. A remote attacker could use this issue to cause pyOpenSSL to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2018-1000807)

It was discovered that pyOpenSSL incorrectly handled memory when performing
operations on a PKCS #12 store. A remote attacker could possibly use this
issue to cause pyOpenSSL to consume resources, resulting in a denial of
service. (CVE-2018-1000808)

Update instructions:

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

Ubuntu 16.04 LTS:
  python-openssl                  0.15.1-2ubuntu0.2
  python3-openssl                 0.15.1-2ubuntu0.2
