CVE-2026-10118— Poppler 输入验证错误漏洞

一分钟漏洞结论

影响对象
Red Hat Red Hat Enterprise Linux 10
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

Poppler是Poppler开源的一个PDF渲染库。 Poppler存在输入验证错误漏洞，该漏洞源于Splash后端中tilingPatternFill函数存在整数溢出，导致堆内存分配不足，进而造成越界写入，可能导致任意代码执行、信息泄露或拒绝服务。

Vulnerability Title
Poppler: integer overflow in poppler splashoutputdev::tilingpatternfill leads to heap buffer overflow via unchecked dimension multiplication
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in Poppler's Splash backend. A remote attacker could exploit this vulnerability by crafting a malicious PDF file that, when rendered, triggers an integer overflow in the `tilingPatternFill` function. This overflow leads to an undersized heap memory allocation, allowing a subsequent out-of-bounds write. Successful exploitation could result in arbitrary code execution, information disclosure, or denial of service within the context of the application processing the PDF.
