| CVE-2016-4292 | 1 Hancom | 1 Hancom Office 2014 | 2017-01-11 | 6.8 MEDIUM | 7.8 HIGH |
| When opening a Hangul HShow Document (.hpt) and processing a structure within the document, Hancom Office 2014 will use a static size to allocate a heap buffer yet explicitly trust a size from the file when modifying data inside of it. Due to this, an aggressor can corrupt memory outside the bounds of this buffer which can lead to code execution under the context of the application. | |||||
| CVE-2016-4295 | 1 Hancom | 1 Hancom Office 2014 | 2017-01-11 | 6.8 MEDIUM | 7.8 HIGH |
| When opening a Hangul Hcell Document (.cell) and processing a particular record within the Workbook stream, an index miscalculation leading to a heap overlow can be made to occur in Hancom Office 2014. The vulnerability occurs when processing data for a formula used to render a chart via the HncChartPlugin.hplg library. Due to a lack of bounds-checking when incrementing an index that is used for writing into a buffer for formulae, the application can be made to write pointer data outside its bounds which can lead to code execution under the context of the application. | |||||
| CVE-2016-4298 | 1 Hancom | 1 Hancom Office 2014 | 2017-01-11 | 6.8 MEDIUM | 7.8 HIGH |
| When opening a Hangul HShow Document (.hpt) and processing a structure within the document, Hancom Office 2014 will attempt to allocate space for a list of elements using a length from the file. When calculating this length, an integer overflow can be made to occur which will cause the buffer to be undersized when the application tries to copy file data into the object containing this structure. This allows one to overwrite contiguous data in the heap which can lead to code-execution under the context of the application. | |||||
| CVE-2015-2810 | 1 Hancom | 4 Hanword Viewer 2007, Hanword Viewer 2010, Hwp 2014 and 1 more | 2016-12-03 | 7.5 HIGH | N/A |
| Integer overflow in the HwpApp::CHncSDS_Manager function in Hancom Office HanWord processor, as used in Hwp 2014 VP before 9.1.0.2342, HanWord Viewer 2007 and Viewer 2010 8.5.6.1158, and HwpViewer 2014 VP 9.1.0.2186, allows remote attackers to cause a denial of service (crash) and possibly "influence the program's execution flow" via a document with a large paragraph size, which triggers heap corruption. | |||||
