Rapporteret den:

5. dec 2001

Berørte pakker:

ssh

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 3614.
I Mitres CVE-ordbog: CVE-2001-0872.

Yderligere oplysninger:

Hvis UseLogin-funktionen var slået til i ssh kunne lokale brugere overføre environment-variable (inklusive variable som LD_PRELOAD) til login-proceduren. Dette er rettet ved ikke at kopiere environment'et hvis UseLogin er slået til.

Bemærk at i Debians standardkonfiguration er UseLogin ikke slået til.

Dette er rettet i version 1:1.2.3-9.4.

Rettet i:

Debian GNU/Linux 2.2 (potato)
