The SingleDocParser::HandleFlowMap function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote attackers to cause a denial of service (stack consumption and application crash) via a crafted YAML file.

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

  - The SingleDocParser::HandleFlowMap function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote attackers to     cause a denial of service (stack consumption and application crash) via a crafted YAML file.
    (CVE-2018-20574)

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1740-3 advisory.

  - The Scanner::EnsureTokensInQueue function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote attackers to     cause a denial of service (stack consumption and application crash) via a crafted YAML file.
    (CVE-2018-20573)

  - The SingleDocParser::HandleFlowMap function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote attackers to     cause a denial of service (stack consumption and application crash) via a crafted YAML file.
    (CVE-2018-20574)

  - The SingleDocParser::HandleFlowSequence function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote     attackers to cause a denial of service (stack consumption and application crash) via a crafted YAML file.
    (CVE-2019-6285)

  - An issue was discovered in singledocparser.cpp in yaml-cpp (aka LibYaml-C++) 0.6.2. Stack Exhaustion     occurs in YAML::SingleDocParser, and there is a stack consumption problem caused by recursive stack     frames: HandleCompactMap, HandleMap, HandleFlowSequence, HandleSequence, HandleNode. Remote attackers     could leverage this vulnerability to cause a denial-of-service via a cpp file. (CVE-2019-6292)

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