DSA-1841-1 git-core -- lammelsesangreb
- Rapporteret den:
- 25. jul 2009
- Berørte pakker:
- git-core
- Sårbar:
- Ja
- Referencer i sikkerhedsdatabaser:
- I Debians fejlsporingssystem: Fejl 532935.
I Mitres CVE-ordbog: CVE-2009-2108. - Yderligere oplysninger:
-
Man opdagede at git-daemon, der er en del af git-core, et populært distribueret versionsstyringssystem, var sårbar over for lammelsesangreb (denial of service) forårsaget af en programmeringsfejl i håndtering af forespørgsler indeholdende ekstra ikke-genkendte parametre, hvilket medførte en uendelig løkke. Mens det ikke er et problem for dæmonen selv, da alle forespørgsler udløser en ny instans af git-daemon, vil det stadig medføre et meget højt CPU-forbrug og kan måske føre til lammelsesangrebsstilstande.
I den gamle stabile distribution (etch), er dette problem rettet i version 1.4.4.4-4+etch3.
I den stabile distribution (lenny), er dette problem rettet i version 1.5.6.5-3+lenny2.
I distributionen testing (squeeze), er dette problem rettet i version 1:1.6.3.3-1.
I den ustabile distribution (sid), er dette problem rettet i version 1:1.6.3.3-1.
Vi anbefaler at du opgraderer dine git-core-pakker.
