The GD Graphics Library (libgd) is an open-source graphics software library for dynamically manipulating images. It can create many formats of image files including GIFs, JPEGs, PNGs, and WBMPs. GD is extensively used with PHP, where a modified version supporting additional features is included by default as of PHP 4.3 and may be used in PHP 5.3 as well. There is a heap buffer overflow vulnerability has been found in GD Library libgd 2.1.1 and prior. The vulnerability exists when a signed integer was claimed to store the size of chunked data, however, an unsigned integer was used for copying. When a negative integer was set to the size variable, the vulnerable codes will overwrite the heap buffer which may cause denial of service or remote code execution under the current user, which may be web application's privileges. This vulnerability is referred as  CVE-2016-3074 . So, it is time to patch you security devices with latest updates. Have a good time. (Be knowledgeable,

Recent zero days discovered in Microsoft scripting engine and Adobe Flash player are being exploited in the wild. The Microsoft JScript and VBScript engines, as used in Internet Explorer 9 through 11 and other products, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Scripting Engine Memory Corruption Vulnerability" (CVE-2016-0189) Adobe Flash Player 21.0.0.226 and earlier allows remote attackers to execute arbitrary code via unspecified vectors.(CVE-2016-4117) If you haven't patch your Security Devices, it is time to patch to prevent from these.

About an year ago Microsoft announced the plan to retire Internet Explorer. The new browser, Microsoft Edge, is now the default browser in Windows 10. Edge has many security improvements. It does not support legacy technologies such as ActiveX and Browser Helper Objects. The new layout engine, EdgeHTML, is a fork of Trident (the layout engine of Internet Explorer) that has removed all legacy code of older versions of Internet Explorer. EdgeHTML is meant to be fully compatible with the WebKit (the layout engine used by Google Chrome). Does Edge outperform Internet Explorer form a security perspective? We tried to find some clues here. Since August 2015, Microsoft has released "Cumulative Security Update for Microsoft Edge" each month. Below is the number of total CVEs related to IE 11 and Edge in last 9 months: Below is the number of critical CVEs related to IE 11 and Edge in last 9 months: Over past years Microsoft has lost market share in web browser (source
