I Debians felrapporteringssystem: Fel 546656.
I Mitres CVE-förteckning: CVE-2009-2632, CVE-2009-3235.

Ytterligare information:

Det upptäcktes att SIEVE-komponenten i dovecot, en epostserver som stödjer postlådor i mbox- och maildirformat, är sårbar för ett buffertspill vid behandling av SIEVE-skript. Detta kan användas till att höja rättigheterna till systemanvändaren dovecot. En angripare som har möjlighet att installera SIEVE-skript som exekveras av servern har därför möjlighet att läsa och modifiera godtyckliga epostmeddelanden på systemet.

För den gamla stabila utgåvan (Etch) har detta problem rättats i version 1.0.rc15-2etch5.

För den stabila utgåvan (Lenny) har detta problem rättats i version 1:1.0.15-2.3+lenny1.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) har detta problem rättats i version 1:1.2.1-1.

Vi rekommenderar att ni uppgraderar era dovecot-paket.
