DSA-1862-1 linux-2.6 -- utökning av privilegier

Rapporterat den:
2009-08-14
Berörda paket:
linux-2.6
Sårbara:
Ja
Referenser i säkerhetsdatabaser:
I Mitres CVE-förteckning: CVE-2009-2692.
Ytterligare information:

En sårbarhet har upptäckts i Linuxkärnan som kan elda till utökning av privilegier. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

  • CVE-2009-2692

    Tavis Ormandy och Julien Tinnes upptäckte ett problem med hur funktionen sendpage initialiseras i strukturen proto_ops. Lokala användare kan utnyttja denna sårbarhet för att erhålla utökade privilegier.

För den gamla stabila utgåvan (Etch) kommer detta problem att rättas i uppdateringar till linux-2.6 och linux-2.6.24.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.6.26-17lenny2.

Vi rekommenderar att ni uppgraderar era linux-2.6- och user-mode-linux-paket.

Observera: Debian övervakar noga alla kända säkerhetsproblem i alla linuxkärnpaket i alla utgåvor med aktivt säkerhetsstöd. Men med tanke på hur ofta säkerhetsproblem av mindre allvarlig karaktär dyker upp och resurserna som krävs för att göra en uppdatering, kommer mindre allvarliga uppdateringar typiskt inte att släppas för alla kärnor på samma gång. De kommer snarare att släppas på ett något hackigt sätt.
