**Name of the Vulnerable Software and Affected Versions** Internet Explorer (affected versions not specified) **Description** The issue is caused by a buffer overflow. It may allow a remote attacker to execute arbitrary code or cause a denial of service (memory corruption) by 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 Windows versions prior to the fixed version Windows Vista SP2 Windows Server 2008 SP2 and R2 SP1 Windows 7 SP1 **Description** The issue is related to the mishandling of DLL loading, allowing local users to gain privileges via a crafted application. This is due to errors in loading libraries. The exploitation of this issue can enable a local attacker to elevate their privileges using a specially crafted application. To exploit, an attacker must first log on to the target system. **Recommendations** For Windows Vista SP2, update to a version that includes the fix for this issue. For Windows Server 2008 SP2 and R2 SP1, update to a version that includes the fix for this issue. For Windows 7 SP1, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting the loading of DLL files to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Microsoft Internet Explorer versions 8 through 11 **Description** The issue is related to the EditWith feature in Microsoft Internet Explorer, which allows remote attackers to bypass the AppContainer protection mechanism and gain privileges. This can be achieved via a DelegateExecute launch of an arbitrary application, demonstrating a transition from Low Integrity to Medium Integrity. The vulnerability exists due to insufficient access restrictions to certain functions, potentially allowing a script to be run with elevated privileges under specific conditions. However, it does not allow arbitrary code to be run by itself but could be used in conjunction with another vulnerability to take advantage of the elevated privileges. **Recommendations** For Microsoft Internet Explorer versions 8 through 11, 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 **Description** The issue is related to insufficient access restrictions to certain functions in Internet Explorer, allowing a remote attacker to gain elevated privileges via a crafted web site. This can occur when Internet Explorer does not properly validate permissions under specific conditions, potentially allowing a script to be run with elevated privileges. The vulnerability by itself does not allow arbitrary code to be run but could be used in conjunction with another vulnerability to take advantage of the elevated privileges when running arbitrary code. **Recommendations** For Microsoft Internet Explorer versions 10 and 11, 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 Windows versions prior to the fixed version Windows Vista SP2 Windows Server 2008 SP2 and R2 SP1 Windows 7 SP1 Windows 8 Windows 8.1 Windows Server 2012 Gold and R2 Windows RT Gold and 8.1 **Description** The issue allows attackers to bypass an application sandbox protection mechanism and perform unspecified registry actions via a crafted application. An elevation of privilege exists in Microsoft Windows when it improperly allows certain registry interactions from within vulnerable sandboxed applications. An attacker who successfully exploited this vulnerability could improperly interact with the registry and attempt to escape the application sandbox. To exploit the vulnerability, an attacker would have to convince the user to open a specially crafted file. The attacker could then run programs with the privileges of the logged on user. **Recommendations** For Windows Vista SP2, update to a newer version to mitigate the risk. For Windows Server 2008 SP2 and R2 SP1, update to a newer version to mitigate the risk. For Windows 7 SP1, update to a newer version to mitigate the risk. For Windows 8, update to a newer version to mitigate the risk. For Windows 8.1, update to a newer version to mitigate the risk. For Windows Server 2012 Gold and R2, update to a newer version to mitigate the risk. For Windows RT Gold and 8.1, update to a newer version to mitigate the risk. As a temporary workaround, consider restricting access to the registry to minimize the risk of exploitation. Avoid using the `CIERegistryHelper::SetSingleValue` function until a patch is available. Restrict the use of the `Microsoft Internet Explorer` application until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** Microsoft Windows versions prior to the fixed version **Description** The issue allows attackers to bypass an application sandbox protection mechanism and perform unspecified filesystem actions via a crafted application. An elevation of privilege exists in Microsoft Windows when it improperly allows certain filesystem interactions from within vulnerable sandboxed applications. An attacker who successfully exploited this issue could improperly interact with the filesystem and attempt to escape the application sandbox. To exploit the issue, an attacker would have to convince the user to open a specially crafted file. **Recommendations** For Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1, update to a version that includes the fix for this issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
