Multiple vulnerabilities were discovered and corrected in poppler: The Gfx::getPos function in the PDF parser in poppler, allows context-dependent attackers to cause a denial of service via unknown vectors that trigger an uninitialized pointer dereference . The PostScriptFunction::PostScriptFunction function in poppler/Function.cc in the PDF parser in poppler, allows context-dependent attackers to cause a denial of service via a PDF file that triggers an uninitialized pointer dereference . The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in poppler, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a PDF file with a crafted Type1 font that contains a negative array index, which bypasses input validation and which triggers memory corruption . The updated packages have been patched to correct these issues.
