Starting in version 3.1.0 and prior to version 3.1.5, Regular Expression Denial of Service (ReDoS) vulnerability exists in the `Rack::Request::Helpers` module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted `Accept-Encoding` or `Accept-Language` headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS). The fix for CVE-2024-26146 was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5. Users of versions on the 3.1 branch should upgrade to version 3.1.5 to receive the fix.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE

Starting in version 3.1.0 and prior to version 3.1.5, Regular Expression Denial of Service (ReDoS) vulnerability exists in the `Rack::Request::Helpers` module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted `Accept-Encoding` or `Accept-Language` headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS). The fix for CVE-2024-26146 was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5. Users of versions on the 3.1 branch should upgrade to version 3.1.5 to receive the fix.","title":"CVE description"}],"product_status":{"known_not_affected":["SUSE Linux Enterprise High Availability Extension 15 SP2:ruby2.5-rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP2:rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP3:ruby2.5-rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP3:rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP4:ruby2.5-rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP4:rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP5:ruby2.5-rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP5:rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP6:ruby2.5-rubygem-rack","SUSE Linux Enterprise High Availability Extension 15 SP6:rubygem-rack","SUSE Linux Enterprise High Performance Computing 12:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise High Performance Computing 12:rubygem-rack-1_4","SUSE Linux Enterprise Module for Containers 12:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Module for Containers 12:rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP3:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP3:rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP4:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP4:rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP5:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server 12 SP5:rubygem-rack-1_4","SUSE Linux Enterprise Server 12:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server 12:rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP3:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP3:rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP4:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP4:rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP5:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12 SP5:rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12:ruby2.1-rubygem-rack-1_4","SUSE Linux Enterprise Server for SAP Applications 12:rubygem-rack-1_4","openSUSE Leap 15.5:ruby2.5-rubygem-rack","openSUSE Leap 15.5:ruby2.5-rubygem-rack-1_6","openSUSE Leap 15.5:ruby2.5-rubygem-rack-doc","openSUSE Leap 15.5:ruby2.5-rubygem-rack-doc-1_6","openSUSE Leap 15.5:ruby2.5-rubygem-rack-testsuite","openSUSE Leap 15.5:ruby2.5-rubygem-rack-testsuite-1_6","openSUSE Leap 15.5:rubygem-rack","openSUSE Leap 15.5:rubygem-rack-1_6","openSUSE Leap 15.6:ruby2.5-rubygem-rack","openSUSE Leap 15.6:ruby2.5-rubygem-rack-1_6","openSUSE Leap 15.6:ruby2.5-rubygem-rack-doc","openSUSE Leap 15.6:ruby2.5-rubygem-rack-doc-1_6","openSUSE Leap 15.6:ruby2.5-rubygem-rack-testsuite","openSUSE Leap 15.6:ruby2.5-rubygem-rack-testsuite-1_6","openSUSE Leap 15.6:rubygem-rack","openSUSE Leap 15.6:rubygem-rack-1_6"]},"references":[{"category":"external","summary":"CVE-2024-39316","url":"https://www.suse.com/security/cve/CVE-2024-39316"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1227310 for CVE-2024-39316","url":"https://bugzilla.suse.com/1227310"}],"threats":[{"category":"impact","date":"2024-07-02T18:08:07Z","details":"moderate"}],"title":"CVE-2024-39316"}]}
