Ytterligare information:

Flera sårbarheter har upptäckts i telnetklienter, vilka kunde utnyttjas av elakartade servrar klienten ansluter till. Projektet Common Vulnerabilities and Exposures project identifierar följande problem:

  • CAN-2005-0468

    Gaël Delalleau upptäckte ett buffertspill i funktionen env_opt_add(), vilket gjorde det möjligt för en angripare att exekvera godtycklig kod.

  • CAN-2005-0469

    Gaël Delalleau upptäckte ett buffertspill i hanteringen av LINEMODE-underalternativen i telnetklienter. Detta kan leda till exekvering av godtycklig kod vid anslutning till en elakartad server.

För den stabila utgåvan (Woody) har dessa problem rättats i version 1.2.4-5woody8.

För den instabila utgåvan (Sid) har dessa problem rättats i version 1.3.6-1.

Vi rekommenderar att ni uppgraderar ert krb5-paket.
