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. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
