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.\r\n\r\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)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"ppp","purl":"pkg:rpm/openEuler/ppp&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.5.0-6.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["ppp-2.5.0-6.oe2403sp3.aarch64.rpm","ppp-debuginfo-2.5.0-6.oe2403sp3.aarch64.rpm","ppp-debugsource-2.5.0-6.oe2403sp3.aarch64.rpm","ppp-devel-2.5.0-6.oe2403sp3.aarch64.rpm"],"noarch":["ppp-help-2.5.0-6.oe2403sp3.noarch.rpm"],"src":["ppp-2.5.0-6.oe2403sp3.src.rpm"],"x86_64":["ppp-2.5.0-6.oe2403sp3.x86_64.rpm","ppp-debuginfo-2.5.0-6.oe2403sp3.x86_64.rpm","ppp-debugsource-2.5.0-6.oe2403sp3.x86_64.rpm","ppp-devel-2.5.0-6.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4116"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75883"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}],"database_specific":{"severity":"Medium"}}
