{"id":"OESA-2025-1918","summary":"polkit security update","details":"polkit is a toolkit for defining and handling authorizations. It is used for allowing unprivileged processes to speak to privileged processes.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file properly.(CVE-2025-7519)","modified":"2026-08-18T01:18:55.712444984Z","published":"2025-08-01T11:09:00Z","upstream":["CVE-2025-7519"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2025-1918"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-7519"}],"affected":[{"package":{"name":"polkit","ecosystem":"openEuler:22.03-LTS-SP3","purl":"pkg:rpm/openEuler/polkit&distro=openEuler-22.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.120-11.oe2203sp3"}]}],"ecosystem_specific":{"aarch64":["polkit-0.120-11.oe2203sp3.aarch64.rpm","polkit-debuginfo-0.120-11.oe2203sp3.aarch64.rpm","polkit-debugsource-0.120-11.oe2203sp3.aarch64.rpm","polkit-devel-0.120-11.oe2203sp3.aarch64.rpm","polkit-libs-0.120-11.oe2203sp3.aarch64.rpm"],"noarch":["polkit-help-0.120-11.oe2203sp3.noarch.rpm"],"src":["polkit-0.120-11.oe2203sp3.src.rpm"],"x86_64":["polkit-0.120-11.oe2203sp3.x86_64.rpm","polkit-debuginfo-0.120-11.oe2203sp3.x86_64.rpm","polkit-debugsource-0.120-11.oe2203sp3.x86_64.rpm","polkit-devel-0.120-11.oe2203sp3.x86_64.rpm","polkit-libs-0.120-11.oe2203sp3.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2025-1918.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
