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"}
