Ytterligare information:

Man har upptäckt flera sårbarheter i Linuxkärnan, vilka kunde användas i en överbelastningsattack eller till exekvering av godtycklig kod. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

  • CVE-2008-3272

    Tobias Klein rapporterade om en dataläcka i funktionen snd_seq_oss_synth_make_info() som kunde utnyttjas lokalt. Detta kunde göra det möjligt för lokala användare att få tillgång till känslig information.

  • CVE-2008-3275

    Zoltan Sogor upptäckte ett kodningsfel i VFS, vilket gjorde det möjligt för lokala användare att utnyttja en läcka i kärnminnet till att utföra en överbelastningsattack.

  • CVE-2008-3276

    Eugene Teo rapporterade ett heltalsspill i DCCP-undersystemet, vilket kunde göra det möjligt för angripare utifrån att utföra en överbelastningsattack i formen av en kärnpanik.

  • CVE-2008-3526

    Eugene Teo rapporterade om en saknad begränsningskontroll i SCTP-undersystemet. Genom att utnyttja ett heltalsspill i koden som hanterade SCTP_AUTH_KEY kunde angripare utifrån kanske utföra en överbelastningsattack i formen av en kärnpanik.

  • CVE-2008-3534

    Kel Modderman rapporterade ett problem i tmpfs-filsystemet vilket gjorde det möjligt för lokala användare att krascha systemet genom att utlösa en BUG()-försäkran i kärnan.

  • CVE-2008-3535

    Alexey Dobriyan upptäckte ett stegfel i funktionen iov_iter_advance, vilket kunde utnyttjas av en lokal användare till att krascha systemet, vilket kunde användas i en överbelastningsattack.

  • CVE-2008-3792

    Vlad Yasevich rapporterade flera referenser till NULL-pekare i SCTP-undersystemet, vilka kunde utlösas genom att gå in i sctp-auth-kodvägar när AUTH-funktionen var inaktiv. Detta kunde kanske göra det möjligt för angripare att utföra en överbelastningsattack i formen av en systempanik.

  • CVE-2008-3915

    Johann Dahm och David Richter rapporterade ett problem i nfsd-undersystemet, vilket kunde göra det möjligt för en angripare utifrån att utföra en överbelastningsattack via ett buffertspill.

För den stabila utgåvan (Etch) har dessa problem rättats i version 2.6.24-6~etchnhalf.5.

Vi rekommenderar att ni uppgraderar era linux-2.6.24-paket.
