Berørte pakker:
dovecot
Sårbar:
Ja
Referencer i sikkerhedsdatabaser:
I Debians fejlsporingssystem: Fejl 546656.
I Mitres CVE-ordbog: CVE-2009-2632, CVE-2009-3235.
Yderligere oplysninger:

Man opdagede at SIEVE-komponenten i dovecot, en mailserver der understøtter mbox- og maildir-mailbokse, var sårbar over for et bufferoverløb når der blev behandlet SIEVE-skripter. Det kunne anvendes til at forøge rettighederne hørende til systembrugeren dovecot. En angriber, der har mulighed for at installere SIEVE-skripter udført på serveren, havde derfor mulighed for at læse og ændre vilkårlige e-mail-meddelelser på systemet.

I den gamle stabile distribution (etch), er dette problem rettet i version 1.0.rc15-2etch5.

I den stabile distribution (lenny), er dette problem rettet i version 1:1.0.15-2.3+lenny1.

I distributionen testing (squeeze) og i den ustabile distribution (sid), er dette problem rettet i version 1:1.2.1-1.

Vi anbefaler at du opgraderer dine dovecot-pakker.
