According to the versions of the grpc package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects     between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS     attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser     The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because     that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected     by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string     reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8     or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0's can be added at the     start of an integer. gRPC's hpack parser needed to read all of them before concluding a parse. - gRPC's     metadata overflow check was performed per frame, so that the following sequence of frames could cause     infinite buffering: HEADERS: containing a: 1 CONTINUATION: containing a: 2 CONTINUATION: containing a: 3     etc (CVE-2023-33953)

  - Lack of error handling in the TCP server in Google's gRPC starting version 1.23 on posix-compatible     platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number     of connections with the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC Java, and Go     are NOT affected. (CVE-2023-4785)

An update of the grpc package has been released.

The version of Oracle Business Intelligence Enterprise Edition (OAS) 7.0.0.0 installed on the remote host is affected by multiple vulnerabilities as referenced in the January 2025 CPU advisory, including the following:

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Analytics Server (SciPy)). Supported versions that are affected are 7.0.0.0.0 and 7.6.0.0.0.     Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to     compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this vulnerability can     result in takeover of Oracle Business Intelligence Enterprise Edition. (CVE-2023-29824)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Platform Security (OpenSSL)). Supported versions that are affected are 7.0.0.0.0, 7.6.0.0.0     and 12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via     TLS to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this     vulnerability can result in unauthorized access to critical data or complete access to all Oracle Business     Intelligence Enterprise Edition accessible data and unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of Oracle Business Intelligence Enterprise Edition. (CVE-2024-5535)

  - Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics     (component: Analytics Server, Pipeline Test Failures, Installation (Spring Framework)). Supported versions     that are affected are 7.0.0.0.0, 7.6.0.0.0 and 12.2.1.4.0. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Oracle Business Intelligence     Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause     a partial denial of service (partial DOS) of Oracle Business Intelligence Enterprise Edition.     (CVE-2024-38809)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0573-1 advisory.

  - When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame.
    This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables     between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests     from the proxy being interpreted as containing headers from different proxy clients - leading to an     information leak that can be used for privilege escalation or data exfiltration. We recommend upgrading     beyond the commit contained in https://github.com/grpc/grpc/pull/33005     https://github.com/grpc/grpc/pull/33005 (CVE-2023-32731)

  - gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy     and a gRPC server: a base64 encoding error for `-bin` suffixed headers will result in a disconnection by     the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyond the commit in     https://github.com/grpc/grpc/pull/32309 https://www.google.com/url (CVE-2023-32732)

  - gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects     between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS     attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser     The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because     that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected     by the client.

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation     can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Lack of error handling in the TCP server in Google's gRPC starting version 1.23 on posix-compatible     platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number     of connections with the server.
