SCA: security update for org.eclipse.jetty.http2:http2-hpack, org.eclipse.jetty.http3:http3-qpack (GHSA-wgh7-54f2-x98r)

high Tenable Self-Hosted Container Security Plugin ID 419917

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Eclipse Jetty provides a web server and servlet container. 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 exceed 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 will 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. (CVE-2023-36478)
