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.
