**Name of the Vulnerable Software and Affected Versions** Cisco AnyConnect Secure Mobility Client for Windows (affected versions not specified) **Description** A vulnerability in the DLL loading mechanism could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed. This issue is due to a race condition in the signature verification process for DLL files. An attacker could exploit this by sending crafted interprocess communication (IPC) messages to the AnyConnect process, potentially allowing the execution of arbitrary code with SYSTEM privileges. The attacker must have valid credentials on the Windows system to exploit this vulnerability. **Recommendations** To resolve the issue, update the Cisco AnyConnect Secure Mobility Client for Windows to a version that includes the fix for this vulnerability. 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** Cisco AnyConnect Secure Mobility Client for Windows (affected versions not specified) **Description** A vulnerability in the interprocess communication (IPC) channel could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed. This issue is due to insufficient validation of resources loaded by the application at run time. An attacker could exploit this by sending a crafted IPC message to the AnyConnect process, potentially allowing the execution of arbitrary code on the affected machine with SYSTEM privileges. The attacker needs valid credentials on the Windows system to exploit this vulnerability. **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** Cisco Webex Meetings Desktop App versions prior to 33.6.6 and 33.9.1 Cisco Webex Productivity Tools versions prior to 33.0.7 **Description** A vulnerability in the update service could allow an authenticated, local attacker to execute arbitrary commands as a privileged user due to insufficient validation of user-supplied parameters. An attacker could exploit this by invoking the update service command with a crafted argument, potentially running arbitrary commands with SYSTEM user privileges. In Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools. **Recommendations** For Cisco Webex Meetings Desktop App versions prior to 33.6.6 and 33.9.1, update to Release 33.6.6 or 33.9.1. For Cisco Webex Productivity Tools versions prior to 33.0.7, update to Release 33.0.7. As a temporary workaround, consider restricting access to the update service command until a patch is applied.

**Name of the Vulnerable Software and Affected Versions** Embarcadero Delphi XE6 version 20.0.15596.9843 C++ Builder XE6 version 20.0.15596.9843 **Description** The issue is related to a buffer overflow in the Vcl.Graphics.TPicture.Bitmap implementation. This allows remote attackers to execute arbitrary code via a crafted BMP file. **Recommendations** For Embarcadero Delphi XE6 version 20.0.15596.9843, consider avoiding the use of the Vcl.Graphics.TPicture.Bitmap implementation until a patch is available. For C++ Builder XE6 version 20.0.15596.9843, consider avoiding the use of the Vcl.Graphics.TPicture.Bitmap implementation until a patch is available.

**Name of the Vulnerable Software and Affected Versions** IcoFX versions 2.5 and earlier **Description** The issue allows remote attackers to execute arbitrary code via a long `idCount` value in an `ICONDIR` structure in an ICO file. This is a stack-based buffer overflow. **Recommendations** For IcoFX versions 2.5 and earlier, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
