CVE-2009-0756

Status Candidate

Overview

The JBIG2Stream::readSymbolDictSeg function in Poppler before 0.10.4 allows remote attackers to cause a denial of service (crash) via a PDF file that triggers a parsing error, which is not properly handled by JBIG2SymbolDict::~JBIG2SymbolDict and triggers an invalid memory dereference.
