CVE-2026-45185, found by XBOW's Federico Kirschbaum and patched in Exim 4.99.3, lets an unauthenticated SMTP client corrupt the heap via a TLS close_notify during a CHUNKING transfer.

An integer overflow in PgBouncer's SCRAM packet parser lets unauthenticated attackers crash the pooler, and three more flaws ship in the same release. Debian stable, testing, and pre-release archives are all still vulnerable.
