Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 279680, Fejl 278278, Fejl 205600.
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 11286.
I Mitres CVE-ordbog: CVE-2004-0968, CVE-2004-1382.

Yderligere oplysninger:

Flere usikre anvendelser af midlertidige filer er opdaget i supportskripter i libc6-pakken, der stiller c-biblioteket til rådighed på GNU/Linux-systemer. Trustix-udviklere har fundet ud af at skriptet catchsegv anvender midlertidige filer på usikker vis. Openwall-udviklere har opdaget usikre midlertidige filer i skriptet glibcbug. Disse skripter er sårbare overfor et symlink-angreb.

I den stabile distribution (woody) er disse problemer rettet i version 2.2.5-11.8.

I den ustabile distribution (sid) er disse problemer rettet i version 2.3.2.ds1-20.

Vi anbefaler at du opgraderer din libc6-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
