Add CVE-2019-12761 to PyXDG
From https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2019-12761
A code injection issue was discovered in PyXDG before 0.26 via crafted Python code in a Category element of a Menu XML document in a .menu file. XDG_CONFIG_DIRS must be set up to trigger xdg.Menu.parse parsing within the directory containing this file. This is due to a lack of sanitization in xdg/Menu.py before an eval call.
