I Mitres CVE-ordbog: CVE-2005-0468, CVE-2005-0469.
CERTs noter om sårbarheder, bulletiner og hændelser: VU#341908, VU#291924.
Yderligere oplysninger:

Flere problemer er opdaget i telnet-klienter, problemerne kunne udnyttes af ondsindede dæmoner som klienterne forbinder sig til. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende problemer:

  • CAN-2005-0468

    Gaël Delalleau har opdaget et bufferoverløb i funktionen env_opt_add(), der gør det muligt for en fjernangriber at udføre vilkårlig kode.

  • CAN-2005-0469

    Gaël Delalleau har opdaget et bufferoverløb i håndteringen af LINEMODE-undervalgmulighederne i telnet-klienter. Dette kunne føre til udførelse af vilkårlig kode, når man var forbundet til en ondsindet server.

I den stabile distribution (woody) er disse problemer rettet i version 1.2.4-5woody8.

I den ustabile distribution (sid) er disse problemer rettet i version 1.3.6-1.

Vi anbefaler at du opgraderer din krb5-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
