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

  - Netty is a network application framework for development of protocol servers and clients. Prior to
    versions 4.1.135.Final and 4.2.15.Final, netty_unix_socket_recvFd sets msg_control to `char
    control[CMSG_SPACE(sizeof(int))]` (line 940) — 24 bytes on 64-bit Linux. A peer-sent SCM_RIGHTS cmsg
    carrying two ints has cmsg_len = CMSG_LEN(8) = 24, which fits exactly with no MSG_CTRUNC, so the kernel
    installs both fds in the receiving process. The subsequent check `cmsg->cmsg_len == CMSG_LEN(sizeof(int))`
    (line 972, expected 20) fails, the branch that would read the fd is skipped, and neither installed fd is
    closed. The for(;;) loop calls recvmsg again (non-blocking → EAGAIN → Java maps to 0 → read loop exits
    normally), leaving two leaked fds per message. There is no MSG_CTRUNC handling. Reachable via Epoll/KQueue
    DomainSocketChannel when the application opts into DomainSocketReadMode.FILE_DESCRIPTORS (non-default).
    Versions 4.1.135.Final and 4.2.15.Final patch the issue. (CVE-2026-45536)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of IBM Cognos Analytics installed on the remote host is 12.0.4 prior to 12.0.4 FP3, or 12.1.x prior to 12.1.3 FP2. It is, therefore, affected by multiple vulnerabilities as referenced in the IBM Security Bulletin No.
7287209:

  - NLTK versions 3.9.2 and prior are vulnerable to arbitrary code execution due to improper input     validation in the StanfordSegmenter module. The module dynamically loads external Java .jar files     without verification or sandboxing. An attacker can supply or replace the JAR file, enabling the     execution of arbitrary Java bytecode at import time. (CVE-2026-0848)

  - The lodash fix for CVE-2021-23337 added validation for the variable option in _.template but did not     apply the same validation to options.imports key names. Both paths flow into the same Function()     constructor sink. When an application passes untrusted input as options.imports key names, an attacker     can inject default-parameter expressions that execute arbitrary code at template compilation time.
    (CVE-2026-4800)

  - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
    From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python     buffers (e.g. Hash.update()), this could lead to buffer overflows. (CVE-2026-39892)
