Quick assessment

Affected

Red Hat Red Hat Enterprise Linux 10

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.

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

Source: 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.
