Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in Python. Software Description: - python2.7: An interactive high-level object-oriented language - python3.7: An interactive high-level object-oriented language - python3.6: An interactive high-level object-oriented language - python3.5: An interactive high-level object-oriented language Details: It was discovered that Python incorrectly handled certain pickle files. An attacker could possibly use this issue to consume memory, leading to a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-20406) It was discovered that Python incorrectly validated the domain when handling cookies. An attacker could possibly trick Python into sending cookies to the wrong domain. (CVE-2018-20852) Jonathan Birch and Panayiotis Panayiotou discovered that Python incorrectly handled Unicode encoding during NFKC normalization. An attacker could possibly use this issue to obtain sensitive information. (CVE-2019-9636, CVE-2019-10160) Colin Read and Nicolas Edet discovered that Python incorrectly handled parsing certain X509 certificates. An attacker could possibly use this issue to cause Python to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-5010) It was discovered that Python incorrectly handled certain urls. A remote attacker could possibly use this issue to perform CRLF injection attacks. (CVE-2019-9740, CVE-2019-9947) Sihoon Lee discovered that Python incorrectly handled the local_file: scheme. A remote attacker could possibly use this issue to bypass blacklist meschanisms. (CVE-2019-9948) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: Ubuntu 18.04 LTS: Ubuntu 16.04 LTS: In general, a standard system update will make all the necessary changes.
