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.

For the stable distribution (sarge) this problem has been fixed in
version 2.23beta1-3sarge2

For the unstable distribution (sid) this problem has been fixed in
version 2.23beta1-5

We recommend that you upgrade your thttpd package.
