This package provides the client applications xfreerdp and wlfreerdp.\r\n\r\nSecurity Fix(es):\n\nFreeRDP before 3.29.0 (affected versions <= 3.28.0) contains an improper certificate hostname validation vulnerability. The TLS hostname matcher (tls_match_hostname() in libfreerdp/crypto/tls.c) treats a wildcard pattern such as *.example.com as matching any hostname ending in .example.com, so it incorrectly accepts a wildcard certificate for multi-label subdomains like a.b.example.com (which OpenSSL's X509_check_host() rejects). This weakens TLS server authentication under wildcard-certificate conditions.(CVE-2026-67293)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"freerdp","purl":"pkg:rpm/openEuler/freerdp&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.11.8-7.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["freerdp-2.11.8-7.oe2403sp3.aarch64.rpm","freerdp-debuginfo-2.11.8-7.oe2403sp3.aarch64.rpm","freerdp-debugsource-2.11.8-7.oe2403sp3.aarch64.rpm","freerdp-devel-2.11.8-7.oe2403sp3.aarch64.rpm","freerdp-help-2.11.8-7.oe2403sp3.aarch64.rpm","libwinpr-2.11.8-7.oe2403sp3.aarch64.rpm","libwinpr-devel-2.11.8-7.oe2403sp3.aarch64.rpm"],"src":["freerdp-2.11.8-7.oe2403sp3.src.rpm"],"x86_64":["freerdp-2.11.8-7.oe2403sp3.x86_64.rpm","freerdp-debuginfo-2.11.8-7.oe2403sp3.x86_64.rpm","freerdp-debugsource-2.11.8-7.oe2403sp3.x86_64.rpm","freerdp-devel-2.11.8-7.oe2403sp3.x86_64.rpm","freerdp-help-2.11.8-7.oe2403sp3.x86_64.rpm","libwinpr-2.11.8-7.oe2403sp3.x86_64.rpm","libwinpr-devel-2.11.8-7.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3644"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67293"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}],"database_specific":{"severity":"Critical"}}
