Several security related problems have been discovered in lurker, an archive tool for mailing lists with integrated search engine. The Common Vulnerabilities and Exposures project identifies the following problems:
Lurker's mechanism for specifying configuration files was vulnerable to being overridden. As lurker includes sections of unparsed config files in its output, an attacker could manipulate lurker into reading any file readable by the www-data user.
It is possible for a remote attacker to create or overwrite files in any writable directory that is named "mbox".
Missing input sanitising allows an attacker to inject arbitrary web script or HTML.
The old stable distribution (woody) does not contain lurker packages.
For the stable distribution (sarge) these problems have been fixed in version 1.2-5sarge1.
For the unstable distribution (sid) these problems have been fixed in version 2.1-1.
We recommend that you upgrade your lurker package.
MD5 checksums of the listed files are available in the original advisory.
