✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: Red Hat recommends upgrading to a fixed release of Python as soon as one is available. This vulnerability can be mitigated by rejecting links inside tarfiles that use relative references to the parent directory. The upstream advisory provides this example code: ''' # Avoid insecure segments in link names. for member in tar.getmembers(): if not member.islnk(): continue if os.pardir in os.path.split(member.linkname): raise OSError("Tarfile with insecure segment ('..') in linkname") # Now safe to extract members with the data filter. tar.extractall(filter="data") '''
