      <title>CVE-2024-6763 — Jetty URI parsing of invalid authority</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-6763</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Eclipse Foundation Jetty, eclipse jetty&lt;/p&gt;
&lt;p&gt;Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine . It includes a utility class, HttpURI, for URI/URL parsing.&lt;/p&gt;
&lt;p&gt;The HttpURI class does insufficient validation on the authority segment of a URI.  However the behaviour of HttpURI
 differs from the common browsers in how it handles a URI that would be 
considered invalid if fully validated against the RRC.  Specifically HttpURI
 and the browser may differ on the value of the host extracted from an 
invalid URI and thus a combination of Jetty and a vulnerable browser may
 be vulnerable to a open redirect attack or to a SSRF attack if the URI 
is used after passing validation checks.&lt;/p&gt;</description>

      <title>GHSA-72hv-8253-57qq — jackson-core: Number Length Constraint Bypass in Async Parser Leads to Potential DoS Condition</title>
      <link>https://vulnerability.circl.lu/vuln/ghsa-72hv-8253-57qq</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Maven: tools.jackson.core:jackson-core, Maven: com.fasterxml.jackson.core:jackson-core&lt;/p&gt;
&lt;p&gt;### Summary
The non-blocking (async) JSON parser in `jackson-core` bypasses the `maxNumberLength` constraint (default: 1000 characters) defined in `StreamReadConstraints`. This allows an attacker to send JSON with arbitrarily long numbers through the async parser API, leading to excessive memory allocation and potential CPU exhaustion, resulting in a Denial of Service (DoS).&lt;/p&gt;
&lt;p&gt;The standard synchronous parser correctly enforces this limit, but the async parser fails to do so, creating an inconsistent enforcement policy.&lt;/p&gt;
&lt;p&gt;### Details
The root cause is that the async parsing path in `NonBlockingUtf8JsonParserBase` (and related classes) does not call the methods responsible for number length validation.&lt;/p&gt;
&lt;p&gt;- The number parsing methods (e.g., `_finishNumberIntegralPart`) accumulate digits into the `TextBuffer` without any length checks.
- After parsing, they call `_valueComplete()`, which finalizes the token but does **not** call `resetInt()` or `resetFloat()`.
- The `resetInt()`/`resetFloat()` methods in `ParserBase` are where the `validateIntegerLength()` and `validateFPLength()` checks are performed.
- Because this validation step is skipped, the `maxNumberLength` constraint is never enforced in the async code path.&lt;/p&gt;
&lt;p&gt;### PoC
The following JUnit 5 test demonstrates the vulnerability. It shows that the async parser accepts a 5,000-digit number, whereas the limit should be 1,000.&lt;/p&gt;
&lt;p&gt;```java
package tools.jackson.core.unittest.dos;&lt;/p&gt;
&lt;p&gt;import java.nio.charset.StandardCharsets;&lt;/p&gt;
&lt;p&gt;import org…&lt;/p&gt;</description>
