Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ppp: reject claimed-as-LCP but actually malformed packets<br /> <br /> Since &amp;#39;ppp_async_encode()&amp;#39; assumes valid LCP packets (with code<br /> from 1 to 7 inclusive), add &amp;#39;ppp_check_packet()&amp;#39; to ensure that<br /> LCP packet has an actual body beyond PPP_LCP header bytes, and<br /> reject claimed-as-LCP but actually malformed data otherwise.
