It includes modules for many different purposes, including the following:\r\n\r\nSecurity Fix(es):\n\nA denial of service vulnerability exists in Twisted framework when handling DNS compression pointer chains. A single malformed TCP packet is sufficient to block the Twisted reactor's event loop for several seconds. Because Twisted operates on a single-threaded cooperative multitasking model, this results in a common Denial of Service (DoS) attack. During this process, the server becomes unable to handle new connections, process I/O, or respond to existing requests, effectively paralyzing the server for the duration of decompression.(CVE-2026-42304)","modified":"2026-05-29T13:45:10.187264977Z","published":"2026-05-29T13:34:08Z","upstream":["CVE-2026-42304"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2488"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42304"}],"affected":[{"package":{"name":"python-twisted","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/python-twisted&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"22.10.0-5.oe2403sp1"}]}],"ecosystem_specific":{"src":["python-twisted-22.10.0-5.oe2403sp1.src.rpm"],"x86_64":["python3-twisted-22.10.0-5.oe2403sp1.x86_64.rpm"],"aarch64":["python3-twisted-22.10.0-5.oe2403sp1.aarch64.rpm"],"noarch":["python-twisted-help-22.10.0-5.oe2403sp1.noarch.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-2488.json"}}],"schema_version":"1.7.5"}
