{"id":"DEBIAN-CVE-2026-85977","details":"A flaw was found in libtirpc. A remote attacker can exploit this vulnerability by sending specially crafted PMAPPROC_DUMP replies to a client application that uses the pmap_getmaps() function against an attacker-controlled host. This unbounded decoding can lead to excessive memory and CPU allocation, causing the client process to experience a Denial of Service (DoS) due to resource exhaustion.","modified":"2026-10-17T10:00:07.481528489Z","published":"2026-10-16T19:17:44.430Z","upstream":["CVE-2026-85977"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-85977"}],"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-2026-85977.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-2026-85977.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-2026-85977.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
