Rapporteret den:

Berørte pakker:

znc

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 516950.
I Mitres CVE-ordbog: CVE-2009-0759.

Yderligere oplysninger:

Man opdagede at znc, en IRC-proxy/-bouncer, ikke på korrekt vis fornuftighedskontrollerede inddata i opsætningsændringsforespørgsler til webadmin-grænsefladen. Det gjorde det muligt for autentificerede brugere at forøge deres rettigheder og indirekte udføre vilkårlige kommandoer (CVE-2009-0759).

I den gamle stabile distribution (etch), er dette problem rettet i version 0.045-3+etch2.

I den stabile distribution (lenny), er dette problem rettet i version 0.058-2+lenny1.

I den ustabile distribution (sid), er dette problem rettet i version 0.066-1.

Vi anbefaler at du opgraderer dine znc-pakker.
