In versions prior to 4.1.129.Final and 4.2.8.Final, the `io.netty.handler.codec.http.HttpRequestEncoder` has a CRLF injection with the request URI when constructing a request. This leads to request smuggling when `HttpRequestEncoder` is used without proper sanitization of the URI. Any application / framework using `HttpRequestEncoder` can be subject to be abused to perform request smuggling using CRLF injection. Versions 4.1.129.Final and 4.2.8.Final fix the issue.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0

In versions prior to 4.1.129.Final and 4.2.8.Final, the `io.netty.handler.codec.http.HttpRequestEncoder` has a CRLF injection with the request URI when constructing a request. This leads to request smuggling when `HttpRequestEncoder` is used without proper sanitization of the URI. Any application / framework using `HttpRequestEncoder` can be subject to be abused to perform request smuggling using CRLF injection. Versions 4.1.129.Final and 4.2.8.Final fix the issue.","title":"CVE description"}],"product_status":{"known_affected":["SUSE Linux Enterprise Module for Package Hub 15 SP6:netty","SUSE Linux Enterprise Module for Package Hub 15 SP6:netty-javadoc","SUSE Linux Enterprise Module for Package Hub 15 SP6:netty-poms","SUSE Manager Server LTS 4.3:netty"],"known_not_affected":["SLES-LTSS-TERADATA 15 SP2:netty3","SUSE Linux Enterprise Desktop 15 SP6:netty3","SUSE Linux Enterprise Desktop 15 SP7:netty3","SUSE Linux Enterprise High Performance Computing 15 SP3-LTSS:netty3","SUSE Linux Enterprise High Performance Computing 15 SP4-LTSS:netty3","SUSE Linux Enterprise High Performance Computing 15 SP5-ESPOS:netty3","SUSE Linux Enterprise High Performance Computing 15 SP5-LTSS:netty3","SUSE Linux Enterprise High Performance Computing 15 SP6:netty3","SUSE Linux Enterprise High Performance Computing 15 SP7:netty3","SUSE Linux Enterprise Module for Development Tools 15 SP6:netty3","SUSE Linux Enterprise Module for Development Tools 15 SP7:netty3","SUSE Linux Enterprise Server 15 SP2-LTSS:netty3","SUSE Linux Enterprise Server 15 SP3-LTSS:netty3","SUSE Linux Enterprise Server 15 SP4-LTSS:netty3","SUSE Linux Enterprise Server 15 SP5-LTSS:netty3","SUSE Linux Enterprise Server 15 SP6-LTSS:netty3","SUSE Linux Enterprise Server 15 SP6:netty3","SUSE Linux Enterprise Server 15 SP7:netty3","SUSE Linux Enterprise Server Teradata 15 SP4:netty3","SUSE Linux Enterprise Server for SAP Applications 15 SP3:netty3","SUSE Linux Enterprise Server for SAP Applications 15 SP4:netty3","SUSE Linux Enterprise Server for SAP Applications 15 SP5:netty3","SUSE Linux Enterprise Server for SAP Applications 15 SP6:netty3","SUSE Linux Enterprise Server for SAP Applications 15 SP7:netty3","openSUSE Leap 15.6:netty3","openSUSE Leap 15.6:netty3-javadoc"],"recommended":["SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-4.1.130-150200.4.40.1","SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Tumbleweed:netty-4.1.130-1.1","openSUSE Tumbleweed:netty-bom-4.1.130-1.1","openSUSE Tumbleweed:netty-javadoc-4.1.130-1.1","openSUSE Tumbleweed:netty-parent-4.1.130-1.1"]},"references":[{"category":"external","summary":"CVE-2025-67735","url":"https://www.suse.com/security/cve/CVE-2025-67735"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1255048 for CVE-2025-67735","url":"https://bugzilla.suse.com/1255048"},{"category":"external","summary":"Advisory link for SUSE-SU-2025:4489-1","url":"https://lists.suse.com/pipermail/sle-security-updates/2025-December/023632.html"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-4.1.130-150200.4.40.1","SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Tumbleweed:netty-4.1.130-1.1","openSUSE Tumbleweed:netty-bom-4.1.130-1.1","openSUSE Tumbleweed:netty-javadoc-4.1.130-1.1","openSUSE Tumbleweed:netty-parent-4.1.130-1.1"]}],"scores":[{"cvss_v3":{"baseScore":6.5,"baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"products":["SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-4.1.130-150200.4.40.1","SUSE Linux Enterprise Module for Package Hub 15 SP7:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-4.1.130-150200.4.40.1","openSUSE Leap 15.6:netty-javadoc-4.1.130-150200.4.40.1","openSUSE Tumbleweed:netty-4.1.130-1.1","openSUSE Tumbleweed:netty-bom-4.1.130-1.1","openSUSE Tumbleweed:netty-javadoc-4.1.130-1.1","openSUSE Tumbleweed:netty-parent-4.1.130-1.1"]}],"threats":[{"category":"impact","date":"2025-12-16T03:02:34Z","details":"moderate"}],"title":"CVE-2025-67735"}]}
