Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2005-2960, CVE-2005-3137.

Yderligere oplysninger:

Javier Fernández-Sanguino Peña har opdaget flere anvendelser af usikre midlertidige filer i cfengine2, et værktøj til opsætning og vedligeholdelse af maskiner i et netværk. Problemet kunne udnyttes via et symlink-angreb til at overskrive vilkårlige filer ejet af bruger der kørte cfengine, hvilket formentlig var root.

Den gamle stabile distribution (woody) er ikke påvirket af dette problem.

I den stabile distribution (sarge) er disse problemer rettet i version 2.1.14-1sarge1.

I den ustabile distribution (sid) vil disse problemer snart blive rettet.

Vi anbefaler at du opgraderer din cfengine2-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
