This enables you to plug your laptop or computer into a network and instantly be able to view other people who you can chat with, find printers to print to or find files being shared. Security Fix(es): Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to the same domain (e.g., "h.local" as a CNAME for "h.local"). This causes unbounded recursion in the lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524.(CVE-2026-24401) An update for avahi is now available for openEuler-22.03-LTS-SP4,openEuler-24.03-LTS,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP2,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.

facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to the same domain (e.g., "h.local" as a CNAME for "h.local"). This causes unbounded recursion in the lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524. 2026-02-28 CVE-2026-24401 openEuler-22.03-LTS-SP4 openEuler-24.03-LTS openEuler-24.03-LTS-SP1 openEuler-24.03-LTS-SP2 openEuler-24.03-LTS-SP3 openEuler-20.03-LTS-SP4 Medium 6.5 AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H avahi security update 2026-02-28 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1450
