RedHat: RHSA-2018-3041:01 Moderate: python security and bug fix update
Summary
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: DOS via regular expression backtracking in difflib.IS_LINE_JUNK
method in difflib (CVE-2018-1061)
* python: DOS via regular expression catastrophic backtracking in apop()
method in pop3lib (CVE-2018-1060)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Red Hat would like to thank the Python security response team for reporting
these issues.
