CVE-ID: CVE-2018-20573
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-6292
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
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.
MitigationUpdate the affected package yaml-cpp to the latest version.
