Summary
Moderate: python38:3.8 security update
Details

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.

Security Fix(es):

  • python: CRLF injection via HTTP request method in httplib/http.client (CVE-2020-26116)

  • python-lxml: mXSS due to the use of improper parser (CVE-2020-27783)

  • python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
