poppler Page class constructor/destructor code execution

poppler-page-destructor-code-execution (43619) The risk level is classified as HighHigh Risk

Description:

poppler could allow a remote attacker to execute arbitrary code on the system, caused by the deletion of an uninitialized pageWidgets object in the Page class constructor/destructor. By persuading a victim to open a specially-crafted PDF file, a remote attacker could invoke a call to an address during the deletion of the object and execute arbitrary code on the vulnerable system.
