{"cve":"CVE-2017-11171","nvd":{"published":"2017-07-11T20:29:00.267","modified":"2026-06-17T01:01:20.880","status":"Modified","description":"Bad reference counting in the context of accept_ice_connection() in gsm-xsmp-server.c in old versions of gnome-session up until version 2.29.92 allows a local attacker to establish ICE connections to gnome-session with invalid authentication data (an invalid magic cookie). Each failed authentication attempt will leak a file descriptor in gnome-session. When the maximum number of file descriptors is exhausted in the gnome-session process, it will enter an infinite loop trying to communicate without success, consuming 100% of the CPU. The graphical session associated with the gnome-session process will stop working correctly, because communication with gnome-session is no longer possible.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-835"],"references":["https://bugzilla.suse.com/show_bug.cgi?id=1025068","https://github.com/GNOME/gnome-session/commit/b0dc999e0b45355314616321dbb6cb71e729fc9d","https://bugzilla.suse.com/show_bug.cgi?id=1025068","https://github.com/GNOME/gnome-session/commit/b0dc999e0b45355314616321dbb6cb71e729fc9d"],"products":["gnome:gnome-session"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-11171","score":0.00322,"percentile":0.25241,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
