| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
yaml-cpp versions 0.5.3 and earlier
Description
The issue allows remote attackers to cause a denial of service, resulting in an assertion failure and application exit. This is achieved by providing a specific string, '!2', which exploits the
Token& Scanner::peek function in scanner.cpp.Recommendations
For yaml-cpp versions 0.5.3 and earlier, consider updating to a newer version to resolve the issue. As a temporary workaround, restrict the input to the
Token& Scanner::peek function to prevent the '!2' string from being processed.Exploit
