In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to\nexceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295\nwill overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server. Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions 11.0.16, 10.0.16, and 9.4.53. There are no known workarounds." } ], "source": { "advisory": "GHSA-wgh7-54f2-x98r", "discovery": "UNKNOWN" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T16:45:57.038Z" }, "title": "CVE Program Container", "references": [ { "name": "https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgh7-54f2-x98r", "tags": [ "x_refsource_CONFIRM", "x_transferred" ], "url": "https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgh7-54f2-x98r" }, { "name": "https://github.com/eclipse/jetty.project/pull/9634", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/eclipse/jetty.project/pull/9634" }, { "name": "https://github.com/eclipse/jetty.project/releases/tag/jetty-10.0.16", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/eclipse/jetty.project/releases/tag/jetty-10.0.16" }, { "name": "https://github.com/eclipse/jetty.project/releases/tag/jetty-11.0.16", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/eclipse/jetty.project/releases/tag/jetty-11.0.16" }, { "name": "https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.53.v20231009", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.53.v20231009" }, { "url": "http://www.openwall.com/lists/oss-security/2023/10/18/4", "tags": [ "x_transferred" ] }, { "url": "https://lists.debian.org/debian-lts-announce/2023/10/msg00045.html", "tags": [ "x_transferred" ] }, { "url": "https://www.debian.org/security/2023/dsa-5540", "tags": [ "x_transferred" ] }, { "url": "https://security.netapp.com/advisory/ntap-20231116-0011/", "tags": [ "x_transferred" ] }, { "url": "https://security.netapp.com/advisory/ntap-20240621-0006/", "tags": [ "x_transferred" ] } ] } ] }, "dataVersion": "5.1" }
