GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.\r\n\r\nSecurity Fix(es):\n\nA denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.(CVE-2026-15588)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"glib2","purl":"pkg:rpm/openEuler/glib2&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.78.3-18.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["glib2-2.78.3-18.oe2403sp1.aarch64.rpm","glib2-debuginfo-2.78.3-18.oe2403sp1.aarch64.rpm","glib2-debugsource-2.78.3-18.oe2403sp1.aarch64.rpm","glib2-devel-2.78.3-18.oe2403sp1.aarch64.rpm","glib2-static-2.78.3-18.oe2403sp1.aarch64.rpm","glib2-tests-2.78.3-18.oe2403sp1.aarch64.rpm"],"noarch":["glib2-help-2.78.3-18.oe2403sp1.noarch.rpm"],"src":["glib2-2.78.3-18.oe2403sp1.src.rpm"],"x86_64":["glib2-2.78.3-18.oe2403sp1.x86_64.rpm","glib2-debuginfo-2.78.3-18.oe2403sp1.x86_64.rpm","glib2-debugsource-2.78.3-18.oe2403sp1.x86_64.rpm","glib2-devel-2.78.3-18.oe2403sp1.x86_64.rpm","glib2-static-2.78.3-18.oe2403sp1.x86_64.rpm","glib2-tests-2.78.3-18.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3241"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15588"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}],"database_specific":{"severity":"Medium"}}
