DSA-1884-1 nginx -- bufferunderløb
- Rapporteret den:
- 14. sep 2009
- Berørte pakker:
- nginx
- Sårbar:
- Ja
- Referencer i sikkerhedsdatabaser:
- I Mitres CVE-ordbog: CVE-2009-2629.
- Yderligere oplysninger:
-
Chris Ries opdagede at nginx, en højtydende HTTP-server, reverse proxy og IMAP/POP3-proxyserver, var sårbar over for et bufferunderløb ved behandling af visse HTTP-forespørgsler. En angriber kunne anvende dette til at udføre vilkårlig kode med rettighederne tilhørende worker-processen (www-data i Debian) eller muligvis iværksætte lammelsesangreb (denial of service) ved gentagne gange at få worker-processen til at gå ned gennem særligt fremstillede URL'er i en HTTP-forespørgsel.
I den gamle stabile distribution (etch), er dette problem rettet i version 0.4.13-2+etch2.
I den stabile distribution (lenny), er dette problem rettet i version 0.6.32-3+lenny2.
I distributionen testing (squeeze), vil dette problem snart blive rettet.
I den ustabile distribution (sid), er dette problem rettet i version 0.7.61-3.
Vi anbefaler at du opgraderer dine nginx-pakker.
