DSA-1862-1 linux-2.6 -- rettighedsforøgelse

Rapporteret den:
14. aug 2009
Berørte pakker:
linux-2.6
Sårbar:
Ja
Referencer i sikkerhedsdatabaser:
I Mitres CVE-ordbog: CVE-2009-2692.
Yderligere oplysninger:

En sårbarhed er opdaget i Linux-kernen, hvilket kunne føre til rettighedsforøgelse. Projektet Common Vulnerabilities and Exposures har registreret følgende problem:

  • CVE-2009-2692

    Tavis Ormandy og Julien Tinnes opdagede et problem med måden hvorved sendpage-funktionen initialiseres i proto_ops-strukturen. Lokale brugere kunne udnytte denne sårbarhed til at opnå forøgede rettigheder.

I den gamle stabile distribution (etch), vil dette problem blive rettet med opdateringer til linux-2.6 og linux-2.6.24.

I den stabile distribution (lenny), er dette problem rettet i version 2.6.26-17lenny2.

Vi anbefaler at du opgraderer dine linux-2.6- og user-mode-linux-pakker.

Bemærk: Debian holder omhyggeligt rede på alle kendte sikkerhedsproblemer i alle linux-kernepakker i alle udgivelser med aktiv sikkerhedsunderstøttelse. Men med den store mængde sikkerhedsproblemer af lav prioritet, der opdages i kernen og ressourcekravene til at foretage en opdatering taget i betragtning, vil opdateringer til problemer af lavere sikkerhedsprioritet typisk ikke blive udgivet til alle kerner på samme tid. I stedet bliver de opsamlet og udgivet i større klumper.
