Memory leak in micronaut-core

Micronaut is a JVM-based, full stack Java framework designed for building JVM web applications with support for Java, Kotlin and the Groovy language. In affected versions sending an invalid Content Type header leads to memory leak in DefaultArgumentConversionContext as this type is erroneously used in static state. ### Impact Sending an invalid Content Type header leads to memory leak in `DefaultArgumentConversionContext` as this type is erroneously used in static state. ### Patches The problem is patched in Micronaut 3.2.7 and above. ### Workarounds The default content type binder can be replaced in an existing Micronaut application to mitigate the issue: ```java package example; import java.util.List; import io.micronaut.context.annotation.Replaces; import io.micronaut.core.convert.ConversionService; import io.micronaut.http.MediaType; import io.micronaut.http.bind.DefaultRequestBinderRegistry; import io.micronaut.http.bind.binders.RequestArgumentBinder; import jakarta.inject.Singleton; @Singleton @Replaces(DefaultRequestBinderRegistry.class) class FixedRequestBinderRegistry extends DefaultRequestBinderRegistry { public FixedRequestBinderRegistry(ConversionService conversionService, List<RequestArgumentBinder> binders) { super(conversionService, binders); } @Override protected void registerDefaultConverters(ConversionService<?> conversionService) { super.registerDefaultConverters(conversionService); conversionService.addConverter(CharSequence.class, MediaType.class, charSequence -> { try { return MediaType.of(charSequence); } catch (IllegalArgumentException e) { return null; } }); } } ``` ### References Commit that introduced the vulnerability https://github.com/micronaut-projects/micronaut-core/commit/b8ec32c311689667c69ae7d9f9c3b3a8abc96fe3 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Micronaut Core](https://github.com/micronaut-projects/micronaut-core/issues) * Email us at [info@micronaut.io](mailto:info@micronaut.io)

Object Computing micronaut 资源管理错误漏洞

Object Computing micronaut是美国Object Computing公司的一款基于JVM的全栈框架，它主要用于构建模块化微服务和无服务器应用程序。 Object Computing Micronaut 存在资源管理错误漏洞，该漏洞源于在受影响的版本中，发送无效的 Content Type 标头会导致 DefaultArgumentConversionContext 中的内存泄漏，因为此类型在静态状态下被错误地使用。 ### Impact 发送无效的 Content Type 标头会导
