The Common Vulnerabilities and Exposures project identifies the following vulnerabilities:

CAN-2002-1562: Information leak 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.

CAN-2003-0899: Arbitrary code execution Joel Soderberg and Christer Oberg 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.");
