    Package        : linux-ftpd
    Vulnerability  : programming error
    Problem-Type   : remote
    Debian-specific: no
    CVE ID         : CVE-2006-5778
    Debian Bug     : 384454
    
    Paul Szabo discovered that the netkit ftp server switches the user id too
    late, which may lead to the bypass of access restrictions when running
    on NFS. This update also adds return value checks to setuid() calls, which
    may fail in some PAM configurations.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 0.17-20sarge2.
    
    For the upcoming stable distribution (etch) this problem has been
    fixed in version 0.17-22.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 0.17-22.
    
    We recommend that you upgrade your ftpd package.
