2018-04-05Ignore bad data in the shared object hint table.Lei Zhang
Currently this is being treated as a case of "data not available" which leads to an infinite loop. BUG=pdfium:1055 Change-Id: I2722a5b364d56a4ad5b7cca2a4b42e6b13a933f4 Reviewed-on: https://pdfium-review.googlesource.com/29831 Commit-Queue: Lei Zhang <thestig@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org>
2018-04-04Decrease XML parser buffer sizeDan Sinclair
This CL decreases the m_iXMLPlaneSize in the CFX_XMLSyntaxParser from 32*1024 to 1024 bytes. This plane size is the size of the chunks we read the XML file in. The issue with having a large plane size is inside the CFX_SeekableStreamProxy::ReadString we allocate a vector of the min(planeSize, remaining_bytes). This means, we could potentially be allocating 32*1024 bytes to read in a single character. For the test in the attached bug the runtime went from 12s to 25ms.
