Debian Security Advisory DSA-1477-1                  security@debian.org

Package        : yarssr
Vulnerability  : missing input sanitising
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-5837

Duncan Gilmore discovered that yarssr, an RSS aggregator and reader,
performs insufficient input sanitising, which could result in the
execution of arbitrary shell commands if a malformed feed is read.

For the stable distribution (etch), this problem has been fixed in
version 0.2.2-1etch1.

Due to a technical limitation of the archive management scripts, the
fix for the old stable distribution (sarge) needs to be postponed
by a few days.

We recommend that you upgrade your yarssr packages.

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.


Debian 4.0 (stable)
- -------------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.

  These files will probably be moved into the stable distribution on
