At present, this package supports IP and IPV6 and the protocols layered above them, such as TCP and UDP.  The Linux port of this package also has support for IPX.\n\nSecurity Fix(es):\n\nThe code in pppd that formats a response to a PEAP Request packet in peap_response() copies an entire TLS record of up to 16384 bytes into the fixed global buffer outpacket_buf\n without checking the available space and without implementing outgoing \nPEAP fragmentation. Thus a pppd process connecting to a server which \nrequests PEAP authentication can be induced to corrupt global static \ndata following the outpacket_buf array, most likely causing incorrect behavior or a crash.(CVE-2026-75883)",
