DSA-483-1 mysql -- usikker oprettelse af midlertidig fil

Rapporteret den:

14. apr 2004

Berørte pakker:

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 10142, BugTraq-id 9976.
I Mitres CVE-ordbog: CVE-2004-0381, CVE-2004-0388.

Yderligere oplysninger:

To sårbarheder er opdaget i mysql, et udbredt databasesystem. To skripter i pakken opretter ikke midlertidige filer på en sikker måde. Dette kunne give en lokal angriber mulighed for at overskrive filer med rettighederne hørende til den bruger, der kørte MySQL-serveren, hvilket ofte er brugeren root. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende problemer:

CAN-2004-0381
Skriptet mysqlbug i MySQL tillader at lokale brugere kan overskrive vilkårlige filer med et symlink-angreb.
CAN-2004-0388
Skriptet mysqld_multi i MySQL tillader at lokale brugere kan overskrive vilkårlige filer via et symlink-angreb.

I den stabile distribution (woody) er disse problemer rettet i version 3.23.49-8.6.

I den ustabile distribution (sid) vil disse problemer blive rettet i version 4.0.18-6 of mysql-dfsg.

Vi anbefaler at du opgraderer dine mysql-, mysql-dfsg- og beslægtede pakker.

Rettet i:

Debian GNU/Linux 3.0 (woody)
