-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Format: 1.8 Date: Wed, 27 May 2026 18:58:40 +0200 Source: exim4 Architecture: source Version: 4.98.2-1+deb13u3 Distribution: trixie-security Urgency: high Maintainer: Exim4 Maintainers Changed-By: Andreas Metzler Changes: exim4 (4.98.2-1+deb13u3) trixie-security; urgency=high . * Cherry-pick fix for EXIM-Security-2026-05-19.1 from 4.99.4. Security: PROXYv2 parser: reject PROXY frames whose declared payload length is too short for the claimed address family (12 bytes for TCPv4/0x11, 36 bytes for TCPv6/0x21). Previously a frame with family=0x21 and len=0 caused 16 bytes of uninitialized stack to be formatted as the sender's IPv6 address and disclosed in the SMTP greeting banner. Affects configurations with SUPPORT_PROXY and `hosts_proxy` set. Reported by Warisjeet Singh (sin99xx).
