Sicherheitsdatenbanken-Referenzen:

In der Debian-Fehlerdatenbank: Fehler 279680, Fehler 278278, Fehler 205600.
In der Bugtraq-Datenbank (bei SecurityFocus): BugTraq ID 11286.
In Mitres CVE-Verzeichnis: CVE-2004-0968, CVE-2004-1382.

Weitere Informationen:

In den Unterstützungsskripten des libc6-Pakets, das die C-Bibliothek eines GNU/Linux-System bereitstellt, wurden mehrere unsichere Verwendungen von temporären Dateien entdeckt. Die Trustix-Entwickler fanden heraus, dass das catchsegv-Skript temporäre Dateien unsicher verwendet. Die Openwall-Entwickler entdeckten unsichere temporäre Dateien im glibcbug-Skript. Diese Skripte sind durch einen Symlink-Angriff verwundbar.

Für die Stable-Distribution (Woody) wurden diese Probleme in Version 2.2.5-11.8 behoben.

Für die Unstable-Distribution (Sid) wurden diese Probleme in Version 2.3.2.ds1-20 behoben.

Wir empfehlen Ihnen, Ihr libc6-Paket zu aktualisieren.

Debian GNU/Linux 3.0 (woody)
