V\u00e4lja on antud parandustootmine posti serverile Exim 4.99.4, mis k\u00f5rvaldab haavatavuse (CVE-2026-48840), mis p\u00f5hjustas 16 mittealgatatud baiti m\u00e4lu lekkimist protsessi-teenindaja stack'ist, esitades kliendile IPv6 aadressi teavet SMTP Hello pealkirjas.

Probleem avaldub alates Exim 4.88 versioonist (2017. aasta) s\u00fcsteemides, mis kasutavad hosts_proxy seadeid ja Exim kompilatsioonid, mis on kompileeritud toetava PROXY valikuga (vaikimisi Debianis, Ubuntu, RHEL EPEL ja Fedoral). Haavatavus tuleneb raamide suuruse n\u00f5uetekohase kontrolli puudumisest PROXYv2 protokolli kasutavate p\u00e4ringute t\u00f6\u00f6tlemisel.
