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 dæmonprogrammer som klienterne forbindes 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-underindstillingen i telnet-klienter. Dette kan føre til udførelse af vilkårlig kode, når klienten er sluttet til en ondsindet server.

I den stabile distribution (woody) er disse problemer rettet i version 1.1-8-2.4.

I distribution testing (sarge) er disse problemer rettet i version 1.2.2-11.2.

I den ustabile distribution (sid) er disse problemer rettet i version 1.2.2-11.2.

Vi anbefaler at du opgraderer dine krb4-pakker.

Rettet i:

Debian GNU/Linux 3.0 (woody)
