SCA: security update for io.netty.incubator:netty-incubator-codec-bhttp (GHSA-q8f2-hxq5-cp4h)

high Tenable Cloud Security Plugin ID 417994

Description

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

 - The netty incubator codec.bhttp is a java language binary http parser. In affected versions the
 `BinaryHttpParser` class does not properly validate input values thus giving attackers almost complete
 control over the HTTP requests constructed from the parsed output. Attackers can abuse several issues
 individually to perform various injection attacks including HTTP request smuggling, desync attacks, HTTP
 header injections, request queue poisoning, caching attacks and Server Side Request Forgery (SSRF).
 Attacker could also combine several issues to create well-formed messages for other text-based protocols
 which may result in attacks beyond the HTTP protocol. The BinaryHttpParser class implements the
 readRequestHead method which performs most of the relevant parsing of the received request. The data
 structure prefixes values with a variable length integer value. The parsing code below first gets the
 lengths of the values from the prefixed variable length integer. After it has all of the lengths and
 calculates all of the indices, the parser casts the applicable slices of the ByteBuf to String. Finally,
 it passes these values into a new `DefaultBinaryHttpRequest` object where no further parsing or validation
 occurs. Method is partially validated while other values are not validated at all. Software that relies on
 netty to apply input validation for binary HTTP data may be vulnerable to various injection and protocol
 based attacks. This issue has been addressed in version 0.0.13.Final. Users are advised to upgrade. There
 are no known workarounds for this vulnerability. (CVE-2024-40642)
