漏洞描述信息
An issue was discovered in the character definitions of the Unicode Specification through 14.0. The specification allows an adversary to produce source code identifiers such as function names using homoglyphs that render visually identical to a target identifier. Adversaries can leverage this to inject code via adversarial identifier definitions in upstream software dependencies invoked deceptively in downstream software. NOTE: the Unicode Consortium offers the following alternative approach to presenting this concern. An issue is noted in the nature of international text that can affect applications that implement support for The Unicode Standard (all versions). Unless mitigated, an adversary could produce source code identifiers using homoglyph characters that render visually identical to but are distinct from a target identifier. In this way, an adversary could inject adversarial identifier definitions in upstream software that are not detected by human reviewers and are invoked deceptively in downstream software. The Unicode Consortium has documented this class of security vulnerability in its document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode Security Mechanisms.

Unicode 安全漏洞
漏洞描述信息
Unicode（通用字符集）是美国统一码联盟（Unicode Consortium）组织的一种通用字符编码标准。用于为世界上每种语言的每个字符和符号分配一个代码。 Unicode Specification 14.0 版本及之前版本存在安全漏洞，该漏洞源于该规范允许攻击者使用在视觉上与目标标识符相同的同形文字生成源代码标识符，例如函数名称。 攻击者可以利用这一点，通过在下游软件中欺骗性地调用的上游软件依赖项中的对抗标识符定义来注入代码。
