Several vulnerabilities have been discovered in thttpd, a tiny HTTP server.
The Common Vulnerabilities and Exposures project identifies the following vulnerabilities:
Marcus Breiing discovered that if thttpd it is used for virtual hosting, and an attacker supplies a specially crafted “Host:” header with a pathname instead of a hostname, thttpd will reveal information about the host system. Hence, an attacker can browse the entire disk.
Joel Söderberg and Christer Öberg discovered a remote overflow which allows an attacker to partially overwrite the EBP register and hence execute arbitrary code.
For the stable distribution (woody) these problems have been fixed in version 2.21b-11.2.
For the unstable distribution (sid) these problems have been fixed in version 2.23beta1-2.3.
We recommend that you upgrade your thttpd package immediately.
