Описание
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.
Отчет
This is an Important heap-based memory corruption flaw in Poppler's Splash backend. Processing a specially crafted PDF document can lead to an integer overflow, resulting in an undersized heap allocation and a subsequent out-of-bounds write. This could allow an attacker to achieve arbitrary code execution, disclose sensitive information, or cause a denial of service within the context of the application rendering the PDF. To successfully exploit this vulnerability the attacker needs to be able to supply the maliciously crafted PDF file to the application consuming poppler or trick the user to process the PDF file using the Poppler's backend.
Меры по смягчению последствий
To mitigate this issue, users should avoid opening untrusted or suspicious PDF documents with applications that utilize the Poppler library for rendering. Limiting exposure to untrusted content can reduce the risk of exploitation.
