Quick assessment
Affected
Red Hat Red Hat build of OpenJDK 11 ELS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
发现 FreeType 中存在一个缺陷，具体位于其 CID 字体加载器中。远程攻击者可通过诱导用户打开嵌入或引用了特制 CID 编码字体的内容来利用此漏洞。该特制字体可引发在多个字体字典中反复分配和解密子程序数据，从而导致内存和 CPU 资源的大量消耗。这可能导致处理该字体的应用程序或服务发生拒绝服务（DoS）攻击，进而使其挂起或终止。

Vulnerability Title
Freetype: freetype: denial of service via repeated subroutine allocations in cid font loader
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in FreeType, specifically within its CID font loader. A remote attacker could exploit this vulnerability by tricking a user into opening content that embeds or references a specially crafted CID-keyed font. This crafted font can cause repeated allocations and decryptions of subroutine data across multiple font dictionaries, leading to excessive memory and CPU consumption. This can result in a denial of service (DoS) for the application or service processing the font, potentially causing it to hang or terminate.
