Package        : thttpd
Vulnerability  : missing input sanitizing, wrong calculation
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2002-1562 CAN-2003-0899

Several vulnerabilities have been discovered in thttpd, a tiny HTTP
server.

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
  hencely execute arbitrary code.

For the stable distribution (woody) these problems have been fixed in
version 2.21b-11.2.

For the unstable distribution (sid) this problem has been fixed in
version 2.23beta1-2.3.

We recommend that you upgrade your thttpd package immediately.
