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

  - The `ecdsa` PyPI package is a pure Python implementation of ECC (Elliptic Curve Cryptography) with support
    for ECDSA (Elliptic Curve Digital Signature Algorithm), EdDSA (Edwards-curve Digital Signature Algorithm)
    and ECDH (Elliptic Curve Diffie-Hellman). Prior to version 0.19.2, an issue in the low-level DER parsing
    functions can cause unexpected exceptions to be raised from the public API functions.
    `ecdsa.der.remove_octet_string()` accepts truncated DER where the encoded length exceeds the available
    buffer. For example, an OCTET STRING that declares a length of 4096 bytes but provides only 3 bytes is
    parsed successfully instead of being rejected. Because of that, a crafted DER input can cause
    `SigningKey.from_der()` to raise an internal exception (`IndexError: index out of bounds on dimension 1`)
    rather than cleanly rejecting malformed DER (e.g., raising `UnexpectedDER` or `ValueError`). Applications
    that parse untrusted DER private keys may crash if they do not handle unexpected exceptions, resulting in
    a denial of service. Version 0.19.2 patches the issue. (CVE-2026-33936)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2026:1436-1 advisory.

    - CVE-2026-33936: issue in the low-level DER parsing functions can cause unexpected exceptions to be     raised from the       public API functions (bsc#1261009).

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

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