The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2023:1408 advisory.
capnp
Rust crate has fixes available in versions 0.13.7, 0.14.11, and 0.15.2. (CVE-2022-46149)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- Cap'n Proto is a data interchange format and remote procedure call (RPC) system. Cap'n Proro prior to
versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3, as well as versions of Cap'n Proto's Rust implementation prior
to 0.13.7, 0.14.11, and 0.15.2 are vulnerable to out-of-bounds read due to logic error handling list-of-
list. This issue may lead someone to remotely segfault a peer by sending it a malicious message, if the
victim performs certain actions on a list-of-pointer type. Exfiltration of memory is possible if the
victim performs additional certain actions on a list-of-pointer type. To be vulnerable, an application
must perform a specific sequence of actions, described in the GitHub Security Advisory. The bug is present
in inlined code, therefore the fix will require rebuilding dependent applications. Cap'n Proto has C++
fixes available in versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3. The `capnp` Rust crate has fixes available in
versions 0.13.7, 0.14.11, and 0.15.2. (CVE-2022-46149)
