Potential privilege escalation vulnerability in Revenera InstallShield versions 2022 R2 and 2021 R2 due to adding InstallScript custom action to a Basic MSI or InstallScript MSI project extracting few binaries to a predefined writable folder during installation time. The standard user account has write access to these files and folders, hence replacing them during installation time can lead to a DLL hijacking vulnerability.

A vulnerability has been reported in Suite Setups built with versions prior to InstallShield 2023 R2. This vulnerability may allow locally authenticated users to cause a Denial of Service (DoS) condition when handling move operations on local, temporary folders.

A vulnerability has been reported in the windows installer (MSI) built with InstallScript custom action. This vulnerability may allow privilege escalation when invoked ‘repair’ of the MSI which has an InstallScript custom action.

Untrusted search path vulnerability in Flexera InstallShield through 2015 SP1 allows local users to gain privileges via a Trojan horse DLL in the current working directory of a setup-launcher executable file.

Flexera Macrovision InstallShield before 2008 sends a digital-signature password to an unintended application during certain signature operations involving .spc and .pvk files, which might allow local users to obtain sensitive information via unspecified vectors, related to an incorrect interaction between InstallShield and Signcode.exe.

The Macrovision InstallShield InstallScript One-Click Install (OCI) ActiveX control 12.0 before SP2 does not validate the DLL files that are named as parameters to the control, which allows remote attackers to download arbitrary library code onto a client machine.

Unspecified vulnerability in the Update Service ActiveX control in isusweb.dll before 6.0.100.65101 in MacroVision FLEXnet Connect and InstallShield 2008 allows remote attackers to execute arbitrary code via an unspecified "unsafe method," possibly involving a buffer overflow.
