Package : thttpd
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: yes
CVE ID : CVE-2006-4248
Debian Bug : 396277


Marco d'Itri discovered that thttpd, a small, fast and secure webserver,
makes use of insecure temporary files when its logfiles are rotated,
which might lead to a denial of service through a symlink attack.
