How to Fix CVE-2023-3635

To remediate this vulnerability, upgrade all affected Okio dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.squareup.okio:okio fixed: 3.4.0 
<dependency>
    <groupId>com.squareup.okio</groupId>
    <artifactId>okio</artifactId>
    <version>3.4.0</version>
</dependency>
com.squareup.okio:okio fixed: 1.17.6 
<dependency>
    <groupId>com.squareup.okio</groupId>
    <artifactId>okio</artifactId>
    <version>1.17.6</version>
</dependency>
com.squareup.okio:okio-jvm fixed: 3.4.0 
<dependency>
    <groupId>com.squareup.okio</groupId>
    <artifactId>okio-jvm</artifactId>
    <version>3.4.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.squareup.okio

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-3635, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.squareup.okio

Analyze the terminal output to locate any version of Okio in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.squareup.okio command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-681: Incorrect Conversion between Numeric Types, where when converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. if the resulting values are used in a sensitive context, then dangerous behaviors may occur. In Okio, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

GzipSource does not handle an exception that might be raised when parsing a malformed gzip buffer. This may lead to denial of service of the Okio client when handling a crafted GZIP archive, by using the GzipSource class.
