**Name of the Vulnerable Software and Affected Versions** Internet Explorer (affected versions not specified) **Description** The issue is related to a lack of protection for sensitive data in Internet Explorer. An attacker could exploit this to gain access to confidential information from the process memory using a specially crafted website. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft Internet Explorer versions 10 through 11 Microsoft Edge (affected versions not specified) **Description** The issue is caused by a type confusion problem in the Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement function in mshtml.dll. This allows remote attackers to execute arbitrary code via vectors involving a crafted Cascading Style Sheets (CSS) token sequence and crafted JavaScript code that operates on a TH element. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, the attacker could take control of an affected system. **Recommendations** For Microsoft Internet Explorer versions 10 through 11, update to a version that is not affected by this issue. For Microsoft Edge, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** FortiClient versions prior to 5.2.4 **Description** The issue allows local users to read arbitrary kernel memory. This is achieved via a specific ioctl call, 0x22608C, to certain drivers, including mdare64 48.sys, mdare32 48.sys, mdare32 52.sys, and mdare64 52.sys. **Recommendations** For versions prior to 5.2.4, update to version 5.2.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the affected drivers to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Fortinet FortiClient versions prior to 5.2.4 **Description** The issue allows local users to execute arbitrary code with kernel privileges. This is achieved by setting the callback function in a (1) 0x220024 or (2) 0x220028 ioctl call, specifically targeting the Fortishield.sys driver. **Recommendations** For versions prior to 5.2.4, update to version 5.2.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the Fortishield.sys driver to minimize the risk of exploitation.
