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

  - Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier,
    Envoy crashes when JWT authentication is configured with the remote JWKS fetching, allow_missing_or_failed
    is enabled, multiple JWT tokens are present in the request headers and the JWKS fetch fails. This is
    caused by a re-entry bug in the JwksFetcherImpl. When the first token's JWKS fetch fails, onJwksError()
    callback triggers processing of the second token, which calls fetch() again on the same fetcher object.
    The original callback's reset() then clears the second fetch's state (receiver_ and request_) which causes
    a crash when the async HTTP response arrives. (CVE-2025-64527)

The version of ecs-service-connect-agent installed on the remote host is prior to v1.34.4.2-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2025-093 advisory.

    There exists a denial of service through Data corruption in gRPC-C++ - gRPC-C++ servers with transmit zero     copy enabled through the channel arg GRPC_ARG_TCP_TX_ZEROCOPY_ENABLED can experience data corruption     issues. The data sent by the application may be corrupted before transmission over the network thus     leading the receiver to receive an incorrect set of bytes causing RPC requests to fail. We recommend     upgrading past commit e9046b2bbebc0cb7f5dc42008f807f6c7e98e791 (CVE-2024-11407)

    LuaJIT through 2.1 has a stack-buffer-overflow in lj_strfmt_wfnum in lj_strfmt_num.c. (CVE-2024-25176)

    LuaJIT through 2.1 has an unsinking of IR_FSTORE for NULL metatable, which leads to Denial of Service     (DoS). (CVE-2024-25177)

    LuaJIT through 2.1 has an out-of-bounds read in the stack-overflow handler in lj_state.c (CVE-2024-25178)

    When libcurl is asked to perform automatic gzip decompression ofcontent-encoded HTTP responses with the     `CURLOPT_ACCEPT_ENCODING` option,**using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow     wouldmake libcurl perform a buffer overflow. (CVE-2025-0725)

    Envoy is an open source L7 proxy and communication bus designed for large modern service oriented     architectures. Versions 1.34.0 through 1.34.4 and 1.35.0 contain a use-after-free (UAF) vulnerability in     the DNS cache, causing abnormal process termination. The vulnerability is in Envoy's Dynamic Forward Proxy     implementation, occurring when a completion callback for a DNS resolution triggers new DNS resolutions or     removes existing pending resolutions. This condition may occur when the following conditions are met:
    dynamic Forwarding Filter is enabled, the `envoy.reloadable_features.dfp_cluster_resolves_hosts` runtime     flag is enabled, and the Host header is modified between the Dynamic Forwarding Filter and Router filters.
    This issue is resolved in versions 1.34.5 and 1.35.1. To work around this issue, set the     envoy.reloadable_features.dfp_cluster_resolves_hosts runtime flag to false. (CVE-2025-54588)

    Envoy is an open source L7 proxy and communication bus designed for large modern service oriented     architectures. In versions below 1.32.10 and 1.33.0 through 1.33.6, 1.34.0 through 1.34.4 and 1.35.0,     insufficient Session Expiration in the Envoy OAuth2 filter leads to failed logout operations. When     configured with __Secure- or __Host- prefixed cookie names, the filter fails to append the required Secure     attribute to the Set-Cookie header during deletion. Modern browsers ignore this invalid request, causing     the session cookie to persist. This allows a user to remain logged in after they believe they have logged     out, creating a session hijacking risk on shared computers. The current implementation iterates through     the configured cookie names to generate deletion headers but does not check for these prefixes. This     failure to properly construct the deletion header means the user's session cookies are never removed by     the browser, leaving the session active and allowing the next user of the same browser to gain     unauthorized access to the original user's account and data. This is fixed in versions 1.32.10, 1.33.7,     1.34.5 and 1.35.1. (CVE-2025-55162)

    Envoy is a cloud-native, open source edge and service proxy. Prior to 1.36.1, 1.35.5, 1.34.9, and 1.33.10,     large requests and responses can potentially trigger TCP connection pool crashes due to flow control     management in Envoy. It will happen when the connection is closing but upstream data is still coming,     resulting in a buffer watermark callback nullptr reference. The vulnerability impacts TCP proxy and HTTP 1     & 2 mixed use cases based on ALPN. This vulnerability is fixed in 1.36.1, 1.35.5, 1.34.9, and 1.33.10.
    (CVE-2025-62409)

    Envoy is an open source edge and service proxy. Envoy versions earlier than 1.36.2, 1.35.6, 1.34.10, and     1.33.12 contain a use-after-free vulnerability in the Lua filter. When a Lua script executing in the     response phase rewrites a response body so that its size exceeds the configured     per_connection_buffer_limit_bytes (default 1MB), Envoy generates a local reply whose headers override the     original response headers, leaving dangling references and causing a crash. This results in denial of     service. Updating to versions 1.36.2, 1.35.6, 1.34.10, or 1.33.12 fixes the issue. Increasing     per_connection_buffer_limit_bytes (and for HTTP/2 the initial_stream_window_size) or increasing     per_request_buffer_limit_bytes / request_body_buffer_limit can reduce the likelihood of triggering the     condition but does not correct the underlying memory safety flaw. (CVE-2025-62504)

    Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier,     when Envoy is configured in TCP proxy mode to handle CONNECT requests, it accepts client data before     issuing a 2xx response and forwards that data to the upstream TCP connection. If a forwarding proxy     upstream from Envoy then responds with a non-2xx status, this can cause a de-synchronized CONNECT tunnel     state. By default Envoy continues to allow early CONNECT data to avoid disrupting existing deployments.
    The envoy.reloadable_features.reject_early_connect_data runtime flag can be set to reject CONNECT requests     that send data before a 2xx response when intermediaries upstream from Envoy may reject establishment of a     CONNECT tunnel. (CVE-2025-64763)

    Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier,     Envoy's mTLS certificate matcher for match_typed_subject_alt_names may incorrectly treat certificates     containing an embedded null byte (\0) inside an OTHERNAME SAN value as valid matches.
