gf2n.cpp in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service (application crash) via DER public-key data for an F(2^m) curve, if the degree of each term in the polynomial is not strictly decreasing.

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

  - gf2n.cpp in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service     (application crash) via DER public-key data for an F(2^m) curve, if the degree of each term in the     polynomial is not strictly decreasing. (CVE-2023-50980)

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

The remote NewStart CGSL host, running version MAIN 7.02, has cryptopp packages installed that are affected by multiple vulnerabilities:

  - ModularSquareRoot in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service     (infinite loop) via crafted DER public-key data associated with squared odd numbers, such as the square of     268995137513890432434389773128616504853. (CVE-2023-50981)

  - gf2n.cpp in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service     (application crash) via DER public-key data for an F(2^m) curve, if the degree of each term in the     polynomial is not strictly decreasing. (CVE-2023-50980)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:0030-1 advisory.

  - gf2n.cpp in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service     (application crash) via DER public-key data for an F(2^m) curve, if the degree of each term in the     polynomial is not strictly decreasing. (CVE-2023-50980)

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

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2023:4957-1 advisory.
