[CLSA-2026:1791469441] alt-python39: Fix of 2 CVEs
Type:
security
Severity:
Critical
Release date:
2026-10-09 07:47:06 UTC
Description:
- CVE-2026-19445: fix use-after-free of a server-side SSLContext when sni_callback switches SSLSocket.context; _servername_callback now holds strong references to the socket's current context and its callback. - CVE-2026-19553: SSLContext.wrap_bio() now raises ValueError when check_hostname is True and no server_hostname is given, like wrap_socket(), instead of silently skipping hostname verification.
