Description:
* SECURITY UPDATE: xml.etree.ElementTree Element.findall(), iterfind()
and find() were vulnerable to a quadratic-complexity CPU denial of
service. Evaluating an XPath index predicate ([1], [last()],
[last()-N]) against a document with many same-tag siblings re-ran
parent.findall(elem.tag) once per candidate element, which is
quadratic in the number of siblings.
- debian/patches/CVE-2026-6879.patch: backport of cpython
2ffab083 (gh-152674). Caches the element selected by the index
predicate per (parent, tag) pair, so each sibling group is
scanned only once.
- CVE-2026-6879
