Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.129.Final and 4.2.8.Final, the `io.netty.handler.codec.http.HttpRequestEncoder` has a CRLF injection with the request URI when constructing a request. This leads to request smuggling when `HttpRequestEncoder` is used without proper sanitization of the URI. Any application / framework using `HttpRequestEncoder` can be subject to be abused to perform request smuggling using CRLF injection. Versions 4.1.129.Final and 4.2.8.Final fix the issue.

The remote Debian 12 / 13 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-6160 advisory.

    Several security vulnerabilities have been discovered in Netty, a Java NIO     client/server socket framework. It was found that Netty was vulnerable to the     MadeYouReset DDoS attack, a logical vulnerability in the HTTP/2 protocol     itself and programming errors which enabled request smuggling attacks.
    Additionally Netty contained an SMTP command injection vulnerability due to     insufficient input validation potentially allowing remote attackers to forge     arbitrary emails from trusted servers.

    The security update for bookworm also contains the fix for CVE-2024-29025.
    Julien Viet discovered that Netty was vulnerable to allocation of resources     without limits or throttling due to the accumulation of data in the     HttpPostRequestDecoder. This would allow an attacker to cause a denial of     service.


    For the oldstable distribution (bookworm), these problems have been fixed     in version 1:4.1.48-7+deb12u2.

    For the stable distribution (trixie), these problems have been fixed in     version 1:4.1.48-10+deb13u1.

    We recommend that you upgrade your netty packages.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the January 2026 CPU advisory.

  - Vulnerability in the Oracle Spatial and Graph (OpenJPEG) component of Oracle Database Server. Supported     versions that are affected are 23.4.0-23.26.0. Easily exploitable vulnerability allows low privileged     attacker having None privilege with logon to the infrastructure where Oracle Spatial and Graph (OpenJPEG)     executes to compromise Oracle Spatial and Graph (OpenJPEG). Successful attacks require human interaction     from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized     ability to cause a partial denial of service (partial DOS) of Oracle Spatial and Graph (OpenJPEG).
    (CVE-2025-54874)

  - Vulnerability in the Fleet Patching and Provisioning (Eclipse Jersey) component of Oracle Database Server.
    Supported versions that are affected are 23.4.0-23.26.0. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Fleet Patching and Provisioning     (Eclipse Jersey). Successful attacks of this vulnerability can result in unauthorized creation, deletion     or modification access to critical data or all Fleet Patching and Provisioning (Eclipse Jersey) accessible     data as well as unauthorized access to critical data or complete access to all Fleet Patching and     Provisioning (Eclipse Jersey) accessible data. (CVE-2025-12383)

  - Vulnerability in the SQLcl component of Oracle Database Server. Supported versions that are affected are     23.4.0-23.26.0. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the     infrastructure where SQLcl executes to compromise SQLcl. Successful attacks require human interaction from     a person other than the attacker. Successful attacks of this vulnerability can result in takeover of     SQLcl. (CVE-2026-21939)

  - Vulnerability in the RDBMS (Python) component of Oracle Database Server. Supported versions that are     affected are 21.3-21.20 and 23.4.0-23.26.0. Easily exploitable vulnerability allows high privileged     attacker having Authenticated User privilege with logon to the infrastructure where RDBMS (Python)     executes to compromise RDBMS (Python). Successful attacks of this vulnerability can result in takeover of     RDBMS (Python). (CVE-2025-13836, CVE-2025-13837, CVE-2025-6069, CVE-2025-6075, CVE-2025-8194,     CVE-2025-8291, CVE-2025-8869)

  - Vulnerability in the Oracle Graal Development Kit for Micronaut (Nimbus JOSE+JWT) component of Oracle     Database Server. Supported versions that are affected are 19.3-19.29 and 23.4.0-23.26.0. Easily     exploitable vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise     Oracle Graal Development Kit for Micronaut (Nimbus JOSE+JWT). Successful attacks of this vulnerability can     result in unauthorized update, insert or delete access to some of Oracle Graal Development Kit for     Micronaut (Nimbus JOSE+JWT) accessible data as well as unauthorized read access to a subset of Oracle     Graal Development Kit for Micronaut (Nimbus JOSE+JWT) accessible data. (CVE-2025-67735)
