(libextractor: Two heap-based buffer overflows)

    Luigi Auriemma has found two heap-based buffer overflows in
    libextractor 0.5.13 and earlier: one of them occurs in the
    asf_read_header function in the ASF plugin, and the other occurs in the
    parse_trak_atom function in the Qt plugin.
  
Impact :

    By enticing a user to open a malformed file using an application
    that employs libextractor and its ASF or Qt plugins, an attacker could
    execute arbitrary code in the context of the application running the
    affected library.
  
Workaround :

    There is no known workaround at this time."
