"The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2023:2783-2 advisory.

  - aaugustin websockets version 4 contains a CWE-409: Improper Handling of Highly Compressed Data (Data
    Amplification) vulnerability in Servers and clients, unless configured with compression=None that can
    result in Denial of Service by memory exhaustion. This attack appear to be exploitable via Sending a
    specially crafted frame on an established connection. This vulnerability appears to have been fixed in 5.
    (CVE-2018-1000518)

  - python-cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, via
    timed processing of valid PKCS#1 v1.5 ciphertext. (CVE-2020-25659)

  - In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrically
    encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the
    Fernet class. (CVE-2020-36242)

  - An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a
    way that would be processed out of order. A small malicious payload can occupy the parser for several
    minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. We
    recommend upgrading libraries beyond the vulnerable versions. (CVE-2021-22569)

  - Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly,
    leading to an unchecked call into the proto file's name during generation of the resulting error message.
    Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or
    greater. (CVE-2021-22570)

  - A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including
    3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including
    3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures.
    A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a
    Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3,
    3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions
    for 3.16 and 3.17 are no longer updated. (CVE-2022-1941)

  - A parsing issue with binary data in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6
    and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated
    embedded messages with repeated or unknown fields causes objects to be converted back-n-forth between
    mutable and immutable forms, resulting in potentially long garbage collection pauses. We recommend
    updating to the versions mentioned above. (CVE-2022-3171)

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