    Synopsis
    ========
    
    Apache Ant uses various insecure temporary files possibly allowing
    local code execution.
    
    Background
    ==========
    
    Ant is a Java-based build tool similar to ‘make’ that uses XML
    configuration files.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  dev-java/ant                 < 1.10.9                  >= 1.10.9 
    
    Description
    ===========
    
    A previous fix for a security vulnerability involving insecure
    temporary files has been found to be incomplete.
    
    Impact
    ======
    
    A local attacker could perform symlink attacks to overwrite arbitrary
    files with the privileges of the user running the application.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All Apache Ant users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-java/ant-1.10.9"
