Release date:
2026-05-07 14:48:36 UTC
Description:
* SECURITY UPDATE: binascii.a2b_base64 / base64.b64decode stop decoding
after the first padded quad, silently dropping any excess data. The
behaviour can lead to data being accepted that other implementations
process differently.
- debian/patches/CVE-2026-3446.patch: backport of upstream commits
4561f6418a (main), e31c55121620 (3.14), 1f9958f909c1 (3.13). Treats
the pad character as non-alphabet data per RFC 4648 section 3.3:
the loop in binascii_a2b_base64 no longer breaks out on a pad
sequence; a `pads` counter is added so post-loop validation still
raises "Incorrect padding" for inputs that do not satisfy
`quad_pos + pads == 4`. The unused `binascii_find_valid` helper
is removed.
