{"id":"DEBIAN-CVE-2026-85231","details":"A flaw was found in libtirpc. An authenticated remote attacker could exploit this vulnerability by sending oversized wrapped data requests to an RPC (Remote Procedure Call) service configured with RPCSEC_GSS (Remote Procedure Call Security-Generic Security Service) integrity or privacy. This can lead to unbounded memory allocation, resulting in a Denial of Service (DoS) by exhausting system resources and causing the service to become unstable or terminate.","modified":"2026-10-17T10:00:07.489815057Z","published":"2026-10-16T19:17:44.180Z","upstream":["CVE-2026-85231"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-85231"}],"affected":[{"package":{"name":"libtirpc","ecosystem":"Debian:12","purl":"pkg:deb/debian/libtirpc?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3+ds-1","1.3.4+ds-1","1.3.4+ds-1.1","1.3.4+ds-1.1~exp1","1.3.4+ds-1.1~exp2","1.3.4+ds-1.2","1.3.4+ds-1.3","1.3.6+ds-1","1.3.7+ds-1","1.3.7-0.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-85231.json"}},{"package":{"name":"libtirpc","ecosystem":"Debian:13","purl":"pkg:deb/debian/libtirpc?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.6+ds-1","1.3.7+ds-1","1.3.7-0.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-85231.json"}},{"package":{"name":"libtirpc","ecosystem":"Debian:14","purl":"pkg:deb/debian/libtirpc?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.6+ds-1","1.3.7+ds-1","1.3.7-0.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-85231.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
