[CLSA-2026:1777629624] alt-python27: Fix of 4 CVEs
Type:
security
Severity:
Important
Release date:
2026-05-01 10:00:29 UTC
Description:
- CVE-2026-1299: email.Generator now rejects header *values* containing CR/LF that are not followed by folding whitespace by raising HeaderWriteError. In Python 2.7 (which lacks BytesGenerator) this single Generator-class hardening covers both upstream CVE-2026-1299 and CVE-2024-6923. - CVE-2024-6923: email.Generator now rejects header *names* containing CR/LF that are not followed by folding whitespace by raising HeaderWriteError, preventing header injection through the header name. - CVE-2024-0397: ssl.SSLContext.cert_store_stats and get_ca_certs now deep-copy the X509_STORE under X509_STORE_lock (via a backport of OpenSSL 3.3's X509_STORE_get1_objects), fixing a memory race when an SSLContext is shared across threads. - CVE-2021-28861: BaseHTTPServer now collapses any leading run of '/' in the request path to a single '/' to prevent an open-redirect via //evil.example/... URIs in 301 Location headers.
