Ytterligare information:

Flera sårbarheter har upptäckts i Linuxkärnan som kan leda till utökning av privilegier, överbelastning eller en informationsläcka. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

  • CVE-2010-2492

    Andre Osterhues rapporterade ett problem i undersystemet eCryptfs. Ett buffertspill kan tillåta lokala användare att orsaka en överbelastning eller erhålla utökade privilegier.

  • CVE-2010-2954

    Tavis Ormandy rapporterade ett problem i undersystemet irda som kan tillåta lokala användare att orsaka en överbelastning med hjälp av en NULL-pekaravreferering.

  • CVE-2010-3078

    Dan Rosenberg upptäckte ett problem i filsystemet XFS som tillåter lokala användare att läsa potentiellt känsligt kärnminne.

  • CVE-2010-3080

    Tavis Ormandy rapporterade ett problem i ALSA-sequencerns OSS-emuleringslager. Lokala användare med tillräckliga rättigheter för att öppna /dev/sequencer (på ett Debiansystem är detta normalt medlemmar i gruppen 'audio') kan orsaka en överbelastning med hjälp av en NULL-pekaravreferering.

  • CVE-2010-3081

    Ben Hawkes upptäckte ett problem i 32-bitskompatibilitetskoden för 64-bitars system. Lokala användare kan erhålla utökade rättigheter på grund av otillräckliga kontroller i compat_alloc_user_space-allokeringar.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.6.26-25lenny1.

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