    Synopsis
    ========
    
    A use-after-free possibly allowing remote execution of code was
    discovered in Transmission.
    
    Background
    ==========
    
    Transmission is a cross-platform BitTorrent client.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-p2p/transmission          < 3.00                     >= 3.00
    
    Description
    ===========
    
    Transmission mishandles some memory management which may allow
    manipulation of the heap.
    
    Impact
    ======
    
    A remote attacker could entice a user to open a specially crafted
    torrent file using Transmission, possibly resulting in execution of
    arbitrary code with the privileges of the process or a Denial of
    Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All Transmission users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-p2p/transmission-3.00"
