[CLSA-2026:1777913923] Fix CVE(s): CVE-2026-1299
Type:
security
Severity:
Important
Release date:
2026-05-04 16:58:49 UTC
Description:
* SECURITY UPDATE: email.generator.BytesGenerator does not validate folded headers, allowing header injection via crafted Header subclasses - debian/patches/CVE-2026-1299.patch: extend verify_generated_headers check to BytesGenerator._write_headers() in Lib/email/generator.py so unsafely folded or delimited headers raise HeaderWriteError on as_bytes() too. Adds matching test coverage in Lib/test/test_email/test_generator.py and test_policy.py. - CVE-2026-1299
