2015-02-10Merge to XFA: Fix heap buffer overflow in CPDF_SampledFunc::v_CallJUN FANG
This issue was caused by integer overflow in CPDF_SampledFunc::v_Call. The root cause of this issue is that the content in the test pdf file was damaged. The solution is to check whether an integer is overflow before using it. BUG=452455 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/886953002

Fix bug with reading from uninitialized variable found by VC++'s /analyze. The flag variable is conditionally initialized but unconditionally read. Warning was: src\fpdfapi\fpdf_page\fpdf_page_pattern.cpp(274) : warning C6001: Using uninitialized memory 'flag'.

2014-10-14Store the address of the page data map's value for proper referencing.Bo Xu
CPDF_Pattern objects are counted and maintained in m_PatternedMap. When a CPDF_Pattern object "pattern" is deleted, it's address is marked as NULL in m_PatternMap. This patch stores the address of CPDF_Pattern's adderss in all objects that references "pattern", to ensure valid referencing after deletion.

2014-10-14Don't leave dangling pointer to out-of-scope local in ↵Tom Sepez
CPDF_StreamContentParser::Parse. This is just a bit of defensive programming; I'm not sure the situation can occur in the current code, but the following code is likely to set off a red flag to anyone who reads it: CPDF_StreamParser syntax(pData, dwSize); m_pSyntax = &syntax; since the extent of the local |syntax| is far less than the pointer member |m_pSyntax|. NULL it out before syntax goes out of scope. R=jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/652063002
2014-09-19Adjust the order of clearing resource in CPDF_DocPageData::ClearJun Fang
Images are basic resource and are referred or used by other objects in some cases. Images should be released after the objects who uses these objects. In this case, an image object is accessed in the process of CPDF_TilingPattern's destroy. Unlikely, this image has been destroyed before.

space in CPDF_ColorSpace::Load The test file defines a wrong color space object (7 0 obj). In the content of 7 0 obj, the reserved obj (0 0 R) is used.

2014-08-05The root cause of this issue is shown as below:Jun Fang
Patterns are managed in CPDF_DocPageData. When a document is closed, all patterns will be released in the deconstruction of CPDF_DocPageData. However, some patterns which are referenced in CPDF_Color can't get the notification from the destroy of CPDF_DocPageData. It will cause use-after-free in CPDF_Color::~CPDF_Color.
