Vulnerability Title
Uncontrolled memory usage in Innodata Labs’ Poppler JPX decoder
Vulnerability Description
Denial-of-service (DoS) vulnerability in the internal JPEG2000 (JPX) decoding implementation of the Poppler fork developed by Innodata Labs. When an application processes an untrusted PDF file containing specially crafted JPXDecode images, a remote attacker can cause uncontrolled memory consumption. The flaw occurs in the JPXStream::readCodestream() function, where values controlled from the SIZ segment (such as img.nComps) are used for the memory allocation of tiles and components without adequate validation. This allows an attacker to force excessive memory allocation and cause a resource exhaustion, ultimately causing the pdftoppm process to terminate due to out-of-memory (OOM) conditions.

Vulnerability Title
Poppler Innodata Labs 资源管理错误漏洞
Vulnerability Description
Poppler Innodata Labs是Poppler组织的一个数据智能与自动化处理平台。 Poppler Innodata Labs 25/08/2026之前版本存在资源管理错误漏洞,该漏洞源于JPXStream::readCodestream()函数在处理SIZ段中受控值时未进行充分验证,导致内存分配过度,造成资源耗尽,最终使进程因内存不足而终止。
