The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-style user and group database files. Versions before 0.4.1 do not sufficiently limit entries when parsing `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file to cause excessive memory consumption and potentially terminate the affected process due to an out-of-memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-controlled user or group database files, or validate and limit untrusted input before parsing it.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-22413fc041 advisory.

    Update to 2.127.0.

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

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3273 advisory.

    containerd is an open-source container runtime. Prior to versions 1.7.36, 2.0.13, 2.2.9, 2.3.6, and 2.4.1,     a crafted OCI index graph can force very high CPU/memory usage during PullImage (before container start),     causing long ContainerCreating stalls and, at larger sizes, node/runtime instability. Versions 1.7.36,     2.0.13, 2.2.9, 2.3.6, and 2.4.1 fix the issue. (CVE-2026-53493)

    Previously, after a channel has been established, a malicious peer could send crafted messages that would     deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled     explicitly. Then, treat all other messages as a protocol error and tear the connection down instead of     buffering and blocking. (CVE-2026-56855)

    The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-     style user and group database files.

    (CVE-2026-61801)

    When Trailer headers are sent by a client, the HTTP server internally uses the header values to populate     the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs     memory overhead. For HTTP/2 servers, a malicious client can exploit this by sending a Trailer header     that declares a large number of fields causing the server to allocate a disproportionate amount of memory     while bypassing Server.MaxHeaderValueCount and Server.MaxHeaderBytes limits.This exploit is not applicable     for HTTP/1 servers, which do not support  multiplexing a large number of requests over one TCP connection,     and whose Server.MaxHeaderBytes are calculated differently.Server.MaxHeaderValueCount and     Server.MaxHeaderBytes limits are now applied towards the trailer fields declared in Trailer headers.

    Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious     peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an     atomic established state, set when a channel becomes usable. Until such a time, handlePacket drops every     packet other than the open confirmation/failure, without blocking and without tearing down the connection.
    (CVE-2026-78662)

    The HTTP/2 server could refund connection-level flow control twice for the same data: Once when a client     resets a stream (refunding data for any sent-but-unread portion of the stream), and again when a request     handler reads the buffered data.A malicious client could exploit this to bypass the configured connection-     level flow control limit (MaxReceiveBufferPerConnection). Total buffered data is still limited by the     concurrent stream limit and stream-level flow control.The HTTP/2 server now waits to refund connection-     level flow control for reset streams until after the request handler is complete.

    OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.5.0 to 1.44.0,     sdk/trace.NewTracerProvider emits a TracerProvider created internal Info-level diagnostic event whose     MarshalLog implementations recursively include span processor, exporter, and client configuration.
    Applications that call otel.SetLogger to enable OpenTelemetry internal Info logging can therefore record     OTLP gRPC and HTTP collector endpoints, the OTLP HTTP Insecure flag, and complete Zipkin collector URLs. A     person or system with access to those logs can learn internal collector topology and can recover     credentials or tokens embedded in Zipkin URL user information or query strings. The default OpenTelemetry     logger does not emit the event, and this path does not log OTLP authentication headers, TLS key material,     or span payloads. This issue is fixed in version 1.45.0. (CVE-2026-81870)

    containerd is an open-source container runtime. From 2.1.0 until 2.2.7 and 2.3.4, containerd's CRI     CreateContainer checkpoint restore is vulnerable because CRIU restores process security state from     checkpoint data instead of enforcing the destination ContainerConfig. An attacker who can create a     container from a crafted checkpoint can supply restored credentials, capabilities, no_new_privs, and     seccomp state. The restored process can run as root with full capabilities and no enforced seccomp filters     while CRI status reports the requested configuration. Systems that do not use CRI checkpoint restore are     not affected. This issue is fixed in versions 2.2.7 and 2.3.4. (CVE-2026-95837)

The version of runc installed on the remote host is prior to 1.4.3-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2026-151 advisory.

    Due to security concerns regarding a small set of intermediate certificates issued by a specific     Certificate Authority (CA), the Go's crypto/x509 package is updated to not trust certificates issued by     the affected intermediate certificates.

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 runc installed on the remote host is prior to 1.4.3-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2NITRO-ENCLAVES-2026-128 advisory.

    Due to security concerns regarding a small set of intermediate certificates issued by a specific     Certificate Authority (CA), the Go's crypto/x509 package is updated to not trust certificates issued by     the affected intermediate certificates. This would prevent possible future misuse of certificate issued by     the affected intermediate certificates. (CVE-2026-111943)

    The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-     style user and group database files. Versions before 0.4.1 do not sufficiently limit entries when parsing     `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file     to cause excessive memory consumption and potentially terminate the affected process due to an out-of-     memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-     controlled user or group database files, or validate and limit untrusted input before parsing it.
