CVE-2017-2790Hig0.578.80.01Feb 24, 2017When processing a record type of 0x3c from a Workbook stream from an Excel file (.xls), JustSystems Ichitaro Office trusts that the size is greater than zero, subtracts one from the length, and uses this result as the size for a memcpy. This results in a heap-based buffer overflow and can lead to code execution under the context of the application.
CVE-2017-2789Hig0.578.80.01Feb 24, 2017When copying filedata into a buffer, JustSystems Ichitaro Office 2016 Trial will calculate two values to determine how much data to copy from the document. If both of these values are larger than the size of the buffer, the application will choose the smaller of the two and trust it to copy data from the file. This value is larger than the buffer size, which leads to a heap-based buffer overflow. This overflow corrupts an offset in the heap used in pointer arithmetic for writing data and can lead to code execution under the context of the application.
CVE-2017-2154Hig0.517.80.00Apr 28, 2017Untrusted search path vulnerability in Hanako 2017, Hanako 2016, Hanako 2015, Hanako Pro 3, JUST Office 3 [Standard], JUST Office 3 [Eco Print Package], JUST Office 3 & Tri-De DataProtect Package, JUST Government 3, JUST Jump Class 2, JUST Frontier 3, JUST School 6 Premium, Hanako Police 5, JUST Police 3, Hanako 2017 trial version allows remote attackers to gain privileges via a Trojan horse DLL in an unspecified directory.
CVE-2017-2791Hig0.497.50.00Feb 24, 2017JustSystems Ichitaro 2016 Trial contains a vulnerability that exists when trying to open a specially crafted PowerPoint file. Due to the application incorrectly handling the error case for a function's result, the application will use this result in a pointer calculation for reading file data into. Due to this, the application will read data from the file into an invalid address thus corrupting memory. Under the right conditions, this can lead to code execution under the context of the application.
CVE-2013-36440.01—0.12Jun 18, 2013Unspecified vulnerability in JustSystems Ichitaro 2006 through 2013; Ichitaro Pro through 2; Ichitaro Government 6, 7, and 2006 through 2010; Ichitaro Portable with oreplug; Ichitaro Viewer; and Ichitaro JUST School through 2010 allows remote attackers to execute arbitrary code via a crafted document.
