{"id":"OESA-2026-3018","summary":"sssd security update","details":"Provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable back end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects like FreeIPA.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit.(CVE-2026-12610)","modified":"2026-07-19T04:00:15.663353526Z","published":"2026-07-19T03:47:51Z","upstream":["CVE-2026-12610"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3018"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12610"}],"affected":[{"package":{"name":"sssd","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/sssd&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.1-25.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["python3-sssd-2.6.1-25.oe2203sp4.aarch64.rpm","sssd-2.6.1-25.oe2203sp4.aarch64.rpm","sssd-debuginfo-2.6.1-25.oe2203sp4.aarch64.rpm","sssd-debugsource-2.6.1-25.oe2203sp4.aarch64.rpm","sssd-devel-2.6.1-25.oe2203sp4.aarch64.rpm"],"noarch":["sssd-help-2.6.1-25.oe2203sp4.noarch.rpm"],"src":["sssd-2.6.1-25.oe2203sp4.src.rpm"],"x86_64":["python3-sssd-2.6.1-25.oe2203sp4.x86_64.rpm","sssd-2.6.1-25.oe2203sp4.x86_64.rpm","sssd-debuginfo-2.6.1-25.oe2203sp4.x86_64.rpm","sssd-debugsource-2.6.1-25.oe2203sp4.x86_64.rpm","sssd-devel-2.6.1-25.oe2203sp4.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3018.json"}}],"schema_version":"1.7.5"}
