More specifically, we don't know of cases where the relevant cpio source code (e.g., copyin.c) has been adapted for use in a library for a long-running process in a different product that also operates on untrusted input, although this might be plausible because a variety of products may want cpio support. A CVE ID may be available if the upstream response indicates that the out-of-bounds reads allow the attacker to change the flow of control. - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCAAGBQJW0HyHAAoJEL54rhJi8gl53eYQAJ+w0oXuIIhSxfJl0amDoBCf nqNdQ9xPq+bHvgDDFwkGdEzutLwDWIG0FmytRbiqXG/u5me4XDQXQ465Kag8n0sG Lzs3dFMDnjz5pd4C7oKx/JhIEjI6rD5oooTqN3xMrPGezaXsz+nL/8AUtFShqGL3 bTIOY0xx4VpR0iTfRu14NpHpB4ocf0OVvSgKHy70H+4TDyM8PKqXSQidkuuHjM8M lhZeMsu5cyBYo2pDqlIHQ4gBhh5+gYDAcUd5Y+C/+DltH2lJjYCRw+KW6utt9/hQ dBzd2VXkNZoFHOnj5AIR2U1ROvpU9eSCxMUPdmKxqrXXOvvxDDaFGaFfHXG0eNR2 n9A67ekWCgUya5wR4nb23olzxvR9GVqkwtRJrZ5z6t/Qrl13LiJArzQRiMdhyydi tkeDw28dHaU2i3XiwZr8x8QSiKx00N5Q0eWOjrigvpbVJVoHQEF2ruIsWm/1L3A/ iJf0JvD2tt1Qh0sNWn+sf+qVnNIywlsRVFP6tiwfsP+cDBqIzH2TyOonDm2tjKeY P/SmiUEm4Btrd6TJnc0uFI3q4p7hfpWbZRC9hgzJKA/k6LUdLuDEUznej7WIHXiQ c8LaZOWsC7cON+4GalayNZnovrE4MCKo4gWMxuecD9/Xv14eE5gpxx8BUL/bM7Ig HX6rsYGYOtDvyyLZqY1o =pd0F -----END PGP SIGNATURE-----
