    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.
    
    Source archives:

      These files will probably be moved into the stable distribution on
      its next update.
