{"id":"UBUNTU-CVE-2026-10028","details":"A flaw was found in glib-networking. A remote attacker can exploit this vulnerability by presenting a specially crafted certificate chain to an application that uses glib-networking with the GnuTLS backend enabled and performs certificate verification. This crafted chain, which contains circular issuer relationships, can cause an infinite loop during certificate verification. The unbounded traversal consumes excessive CPU resources, leading to a denial of service for the affected process or worker.","modified":"2026-06-03T11:20:11Z","published":"2026-05-28T23:16:00Z","upstream":["CVE-2026-10028"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-10028"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-10028"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-10028"}],"affected":[{"package":{"name":"glib-networking","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.46.0-1","2.46.1-1","2.46.1-1build1","2.48.0-1","2.48.2-1~ubuntu16.04.1","2.48.2-1~ubuntu16.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"glib-networking","binary_version":"2.48.2-1~ubuntu16.04.2"},{"binary_version":"2.48.2-1~ubuntu16.04.2","binary_name":"glib-networking-common"},{"binary_name":"glib-networking-services","binary_version":"2.48.2-1~ubuntu16.04.2"},{"binary_version":"2.48.2-1~ubuntu16.04.2","binary_name":"glib-networking-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.54.0-1","2.54.1-1","2.54.1-2","2.55.90-1","2.56.0-1","2.56.0-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.56.0-1ubuntu0.1","binary_name":"glib-networking"},{"binary_version":"2.56.0-1ubuntu0.1","binary_name":"glib-networking-common"},{"binary_name":"glib-networking-services","binary_version":"2.56.0-1ubuntu0.1"},{"binary_version":"2.56.0-1ubuntu0.1","binary_name":"glib-networking-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.62.1-1","2.63.2-1","2.63.3-0build1","2.63.90-1ubuntu1","2.63.91-1ubuntu1","2.64.0-1","2.64.1-1","2.64.2-1build1","2.64.2-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"glib-networking","binary_version":"2.64.2-1ubuntu0.1"},{"binary_name":"glib-networking-common","binary_version":"2.64.2-1ubuntu0.1"},{"binary_name":"glib-networking-services","binary_version":"2.64.2-1ubuntu0.1"},{"binary_name":"glib-networking-tests","binary_version":"2.64.2-1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.68.2-2","2.70.0-1","2.70.1-1","2.72~alpha-1","2.72~beta-1build1","2.72.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"glib-networking","binary_version":"2.72.0-1"},{"binary_name":"glib-networking-common","binary_version":"2.72.0-1"},{"binary_version":"2.72.0-1","binary_name":"glib-networking-services"},{"binary_name":"glib-networking-tests","binary_version":"2.72.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.78.0-1","2.80~alpha-1","2.80~rc-1","2.80.0-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.80.0-1build1","binary_name":"glib-networking"},{"binary_name":"glib-networking-common","binary_version":"2.80.0-1build1"},{"binary_version":"2.80.0-1build1","binary_name":"glib-networking-services"},{"binary_name":"glib-networking-tests","binary_version":"2.80.0-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/glib-networking?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.80.1-1","2.80.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"glib-networking","binary_version":"2.80.1-1build1"},{"binary_version":"2.80.1-1build1","binary_name":"glib-networking-common"},{"binary_version":"2.80.1-1build1","binary_name":"glib-networking-services"},{"binary_version":"2.80.1-1build1","binary_name":"glib-networking-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10028.json"}},{"package":{"name":"glib-networking","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg
