    Synopsis
    ========
    
    A NULL pointer dereference in Openswan may allow remote attackers to
    cause Denial of Service.
    
    Background
    ==========
    
    Openswan is an implementation of IPsec for Linux.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-misc/openswan          <= 2.6.39-r1               Vulnerable!
        -------------------------------------------------------------------
         NOTE: Certain packages are still vulnerable. Users should migrate
               to another package if one is available or wait for the
               existing packages to be marked stable by their
               architecture maintainers.
    
    Description
    ===========
    
    A NULL pointer dereference has been found in Openswan.
    
    Impact
    ======
    
    A remote attacker could create a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    Gentoo has discontinued support for Openswan. We recommend that users
    unmerge Openswan:
    
      # emerge --unmerge "net-misc/openswan"
    
    NOTE: The Gentoo developer(s) maintaining Openswan have discontinued
    support at this time. It may be possible that a new Gentoo developer
    will update Openswan at a later date. Alternatives packages such as
    Libreswan and strongSwan are currently available in Gentoo Portage.
