Package        : slrn
Problem type   : remote command invocation
Debian-specific: no

Byrial Jensen found a nasty problem in slrn (a threaded news reader).
The notice on slrn-announce describes it as follows:

    When trying to decode binaries, the built-in code executes any shell
    scripts the article might contain, apparently assuming they would be
    some kind of self-extracting archive.

This problem has been fixed in version 0.9.6.2-9potato2 by removing
this feature.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.


Debian GNU/Linux 2.2 alias potato
