    Dmitry E. Oboukhov discovered that the "to-upgrade" plugin of Feta, a simpler interface to APT, dpkg, and other Debian package tools creates temporary files insecurely, which may lead to local denial of service through symlink attacks.

    Dmitry E. Oboukhov discovered that the "to-upgrade" plugin of Feta,
    a simpler interface to APT, dpkg, and other Debian package tools
    creates temporary files insecurely, which may lead to local denial
    of service through symlink attacks.
    
    For the stable distribution (etch), this problem has been fixed in
    version 1.4.15+etch1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.4.16+nmu1.
    
    We recommend that you upgrade your feta package.
    
    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 GNU/Linux 4.0 alias etch
    - -------------------------------
    
    Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
    
    Source archives:
    
      http://security.debian.org/pool/updates/main/f/feta/feta_1.4.15+etch1.dsc
        Size/MD5 checksum:      545 87c8cdfc722b149eefc2c4cc1e05c868

        Size/MD5 checksum:    52134 27b5bc566e7f42a5b79dd8ef67013b8d
    
    Architecture independent packages:
    
      http://security.debian.org/pool/updates/main/f/feta/feta_1.4.15+etch1_all.deb
        Size/MD5 checksum:    47708 8133fddc8dc30973c5fcb3368292b1fb
    
      These files will probably be moved into the stable distribution on
      its next update.
