CWE-20  (opens in a new tab)

How to fix?

Upgrade SLES:15.1 libpython3_6m1_0 to version 3.6.10-3.42.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libpython3_6m1_0 package and not the libpython3_6m1_0 package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
