a comprehensive WSGI web application library. Prior to version 2.2.3, Werkzeug's multipart form data parser will parse an unlimited number of parts, including file parts. Parts can be a small amount of bytes, but each requires CPU time to parse and may use more memory as Python data. If a request can be made to an endpoint that accesses `request.data`, `request.form`, `request.files`, or `request.get_data(parse_form_data=False)`, it can cause unexpectedly high resource usage. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requests. The amount of RAM required can trigger an out of memory kill of the process. Unlimited file parts can use up memory and file handles. If many concurrent requests are sent continuously, this can exhaust or kill all available workers. Version 2.2.3 contains a patch for this issue.","title":"CVE description"}],"product_status":{"recommended":["SUSE Enterprise Storage 7:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP1:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP2:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","openSUSE Leap 15.4:python-Werkzeug-doc-0.14.1-150100.6.6.1.noarch"]},"references":[{"category":"external","summary":"CVE-2023-25577","url":"https://www.suse.com/security/cve/CVE-2023-25577"},{"category":"external","summary":"SUSE Bug 1208283 for CVE-2023-25577","url":"https://bugzilla.suse.com/1208283"}],"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 Enterprise Storage 7:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP1:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP2:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","openSUSE Leap 15.4:python-Werkzeug-doc-0.14.1-150100.6.6.1.noarch"]}],"scores":[{"cvss_v3":{"baseScore":7.5,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"products":["SUSE Enterprise Storage 7:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise High Performance Computing 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP1-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server 15 SP2-LTSS:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP1:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","SUSE Linux Enterprise Server for SAP Applications 15 SP2:python3-Werkzeug-0.14.1-150100.6.6.1.noarch","openSUSE Leap 15.4:python-Werkzeug-doc-0.14.1-150100.6.6.1.noarch"]}],"threats":[{"category":"impact","date":"2023-03-29T09:05:33Z","details":"important"}],"title":"CVE-2023-25577"}]}
