[CLSA-2026:1784713984] Fix CVE(s): CVE-2026-15308
Type:
security
Severity:
Important
Release date:
2026-07-22 12:52:01 UTC
Description:
* SECURITY UPDATE: html.parser.HTMLParser was vulnerable to a quadratic-complexity CPU denial of service. Feeding an unterminated markup construct (e.g. a tag or comment) in many small chunks made feed() re-scan and re-concatenate the growing unparsed buffer on every call, which is quadratic in the input size. - debian/patches/CVE-2026-15308.patch: backport of cpython bcf98ddb (gh-153030). Accumulates incoming data in a list and only joins/parses it once enough has piled up, flushing any pending data in close(). - CVE-2026-15308
