Package           : htdig

Vulnerability type: remote exploit

Debian-specific   : no



The version of htdig that was shipped in Debian GNU/Linux 2.1 has a problem

with calling external programs to handle non-HTML documents: it calls

the external program with the document as a parameter, but does not check

for shell escapes. This can be exploited by creating files with filenames

that include shell escapes to run arbitraty commands on the machine that

runs htdig.



This has been fixed in version 3.1.2-4slink6. We recommend you upgrade your

htdig package immediately.



wget url

        will fetch the file for you

dpkg -i file.deb

        will install the referenced file.



Debian GNU/Linux 2.1 alias slink
