CVE-2018-7536 (opens in a new tab)How to fix?
Upgrade RHEL:7 tfm-runtime to version 0:4.0-3.el7sat or higher.
This issue was patched in RHSA-2018:2927.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tfm-runtime package and not the tfm-runtime package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. The django.utils.html.urlize() function was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions (only one regular expression for Django 1.8.x). The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable.
