{"id":"OESA-2026-4821","summary":"glib-networking security update","details":"glib-networking contains the implementations of certain GLib networking features that cannot be implemented directly in GLib itself because of their dependencies.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in glib-networking. When establishing connections using Transport Layer Security (TLS) version 1.3, the client-side session cache does not limit the number of session tickets retained for a single host. A malicious server can exploit this by sending excessive session ticket messages, causing the client application to continuously consume memory. This unbounded memory growth can exhaust system memory, resulting in a Denial of Service (DoS).(CVE-2026-103963)","modified":"2026-11-11T12:45:08.410728660Z","published":"2026-11-11T12:26:31Z","upstream":["CVE-2026-103963"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4821"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103963"}],"affected":[{"package":{"name":"glib-networking","ecosystem":"openEuler:24.03-LTS-SP4","purl":"pkg:rpm/openEuler/glib-networking&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.78.0-6.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["glib-networking-2.78.0-6.oe2403sp4.aarch64.rpm","glib-networking-debuginfo-2.78.0-6.oe2403sp4.aarch64.rpm","glib-networking-debugsource-2.78.0-6.oe2403sp4.aarch64.rpm","glib-networking-tests-2.78.0-6.oe2403sp4.aarch64.rpm"],"src":["glib-networking-2.78.0-6.oe2403sp4.src.rpm"],"x86_64":["glib-networking-2.78.0-6.oe2403sp4.x86_64.rpm","glib-networking-debuginfo-2.78.0-6.oe2403sp4.x86_64.rpm","glib-networking-debugsource-2.78.0-6.oe2403sp4.x86_64.rpm","glib-networking-tests-2.78.0-6.oe2403sp4.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4821.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
