Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2009-0692, CVE-2009-1892.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#410676.

Yderligere oplysninger:

Flere fjernudnytbare sårbarheder er opdaget i ISC's DHCP-implementering:

CVE-2009-0692
Man opdagede at dhclient ikke på korrekt vis håndterede for lange subnet-mask-valgmuligheder, førende til et stakbaseret bufferoverløb og muligvis udførelse af vilkårlig kode.
CVE-2009-1892
Christoph Biedl opdagede at DHCP-server måske ville afslutte, når den modtog visse veldannede DHCP-forespørgsler, forudsat at serveropsætningen kombinerede host-definitioner ved hjælp af "dhcp-client-identifier" og "hardware ethernet". Sårbarheden påvirker kun lenny-versionerne af dhcp3-server og dhcp3-server-ldap.

I den gamle stabile distribution (etch), er disse problemer rettet i version 3.0.4-13+etch2.

I den stabile distribution (lenny), er dette problem rettet i version 3.1.1-6+lenny2.

I den ustabile distribution (sid), vil disse problemer snart blive rettet.

Vi anbefaler at du opgraderer dine dhcp3-pakker.
