Yderligere oplysninger:

Flere fjernudnytbare sårbarheder er opdaget i NTP, referenceimplementeringen af Network Time Protocol. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2009-0159
Et bufferoverløb i ntpq gjorde det muligt for en fjern NTP-server, at iværksætte et lammelsesangreb (denial of service) eller udføre vilkårlig kode gennem et fabrikeret svar.
CVE-2009-1252
Et bufferoverløb i ntpd gjorde det muligt for en fjernangriber, at iværksætte et lammelsesangreb eller udføre vilkårlig kode, når autokey-funktionaliteten var aktiveret.

I den gamle stabile distribution (etch), er disse problemer rettet i version 4.2.2.p4+dfsg-2etch3.

I den stabile distribution (lenny), er disse problemer rettet i version 4.2.4p4+dfsg-8lenny2.

Den ustabile distribution (sid) vil snart blive rettet.

Vi anbefaler at du opgraderer din ntp-pakke.
