Cross-site scripting (XSS) vulnerability in feedparser.py in Universal Feed Parser (aka feedparser or python-feedparser) 5.x before 5.0.1 allows remote attackers to inject arbitrary web script or HTML via malformed XML comments.

Various issues in python-feedparser have been fixed, including fixes for crashes due to missing input sanitizaion and a XSS vulnerability.
CVE-2011-1156, CVE-2011-1157, CVE-2011-1158 and CVE-2009-5065 have been assigned to these issues.

Previous version of python-djblets contained embedded / own copy of python-feedparser (BUILD/Djblets-0.6.22/djblets/feedview feedparser.py) code, which is vulnerable to numerous security flaws (CVE-2009-5065, CVE-2011-1156, CVE-2011-1157, and CVE-2011-1158 to mention some of them).

This package modifies Djblets to use the system copy of feedparser.
