Rapporteret den:

8. nov 2004

Berørte pakker:

gzip

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 11288.
I Mitres CVE-ordbog: CVE-2004-0970.

Yderligere oplysninger:

Trustix-udviklerne har opdaget en usikker oprettelse af midlertidige filer i de supplerende skripter i gzip-pakken, hvilket kan gøre det muligt for lokale brugere at overskrive filer via et symlink-angreb.

I den stabile distribution (woody) er disse problemer rettet i version 1.3.2-3woody3.

The ustabile distribution (sid) er ikke påvirket af disse problemer.

Vi anbefaler at du opgraderer din gzip-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
