{"id":"OESA-2026-4721","summary":"qt6-qtbase security update","details":"Qt is a software toolkit for developing applications.\r\n\r\nSecurity Fix(es):\n\nA NULL pointer dereference vulnerability in the Qt QCborValue to JSON conversion of the Qt Core module.(CVE-2026-105924)\n\nOut-of-bounds read in the QAuthenticator NTLM authentication handling in the Qt Network module in Qt Group Qt allows remote attackers to obtain sensitive information (heap memory contents) or cause a denial of service (application crash) via a crafted NTLM challenge sent by a malicious server or proxy, when an application using QNetworkAccessManager or QTcpSocket authenticates with NTLM.(CVE-2026-105946)\n\nSpecially crafted CBOR input passed to QCborValue::fromCbor() in Qt Core can cause an out-of-bounds read, which may crash the application and could expose information.(CVE-2026-107157)\n\nQDomDocument XML parsing is vulnerable to a remotely-triggerable denial-of-service crash when processing untrusted input.(CVE-2026-19248)\n\nOut-of-bounds read (buffer over-read) in the HTTP Cache-Control response header parsing in the QtNetwork module in Qt Group Qt 6.0.0 through 6.8.8, and 6.9.0 through 6.11.1, allows remote attackers to cause a denial of service (application crash) via an excessively large Cache-Control header value returned by an untrusted or compromised HTTP server to an application using QNetworkAccessManager. Only the client side of the connection is affected and 32-bit builds are not affected; the out-of-bounds access is read-only, with no information disclosure and no code execution.(CVE-2026-76151)","modified":"2026-11-04T14:00:07.383660712Z","published":"2026-11-04T13:54:53Z","upstream":["CVE-2026-105924","CVE-2026-105946","CVE-2026-107157","CVE-2026-19248","CVE-2026-76151"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4721"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105924"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105946"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107157"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-19248"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76151"}],"affected":[{"package":{"name":"qt6-qtbase","ecosystem":"openEuler:24.03-LTS-SP3","purl":"pkg:rpm/openEuler/qt6-qtbase&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.5.2-18.oe2403sp3"}]}],"ecosystem_specific":{"x86_64":["qt6-qtbase-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-debuginfo-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-debugsource-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-devel-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-examples-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-gui-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-ibase-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-mysql-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-odbc-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-postgresql-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-private-devel-6.5.2-18.oe2403sp3.x86_64.rpm","qt6-qtbase-static-6.5.2-18.oe2403sp3.x86_64.rpm"],"aarch64":["qt6-qtbase-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-debuginfo-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-debugsource-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-devel-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-examples-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-gui-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-ibase-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-mysql-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-odbc-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-postgresql-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-private-devel-6.5.2-18.oe2403sp3.aarch64.rpm","qt6-qtbase-static-6.5.2-18.oe2403sp3.aarch64.rpm"],"noarch":["qt6-qtbase-common-6.5.2-18.oe2403sp3.noarch.rpm"],"src":["qt6-qtbase-6.5.2-18.oe2403sp3.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4721.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/AU:N/R:U/V:D/RE:L"}]}
