CVE-2017-8776
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedQuick Heal Internet Security 10.1.0.316, Quick Heal Total Security 10.1.0.316, and Quick Heal AntiVirus Pro 10.1.0.316 have approximately 165 PE files in the default installation that do not use ASLR/DEP protection mechanisms that provide sufficient defense against directed attacks against the product.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceQuick Heal security products (Internet Security, Total Security, and AntiVirus Pro version 10.1.0.316) ship approximately 165 PE (Portable Executable) files without ASLR (Address Space Layout Randomization) and DEP (Data Execution Prevention) protection flags enabled in their headers. This allows attackers to reliably predict memory addresses and execute arbitrary code when other vulnerabilities are present, as these mitigations would otherwise randomize memory layouts and block execution from data segments.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Quick Heal product installationCheck Program Files or Program Files (x86) for 'Quick Heal' folder, or query the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for display names containing 'Quick Heal'. Note the product name (Antivirus Pro, Internet Security, or Total Security) and the installed version.Affected if Quick Heal Antivirus Pro, Internet Security, or Total Security version 10.1.0.316 or lower is installed
-
Locate Quick Heal executable filesNavigate to the Quick Heal installation directory (typically C:\Program Files\Quick Heal\ or C:\Program Files (x86)\Quick Heal\) and identify the PE (.exe and .dll) files present.Affected if PE files exist in the Quick Heal installation folder
-
Inspect PE headers for ASLR flagUse a PE analysis tool such as 'dumpbin /headers' from Visual Studio, or a script using the pefile Python library, to examine each PE file's DLL characteristics field. Check if the 0x0140 bit (IMAGE_DLLCHARACTERISTICS_DYNAMICBASE) is set. This indicates ASLR is enabled.Affected if PE files have DLL characteristics that do NOT include the 0x0140 (DYNAMICBASE) flag - meaning ASLR is not enabled
-
Inspect PE headers for DEP flagUsing the same PE analysis tool, check the DLL characteristics field for the 0x0100 bit (IMAGE_DLLCHARACTERISTICS_NX_COMPAT). This flag indicates Data Execution Prevention (DEP) is enabled.Affected if PE files have DLL characteristics that do NOT include the 0x0100 (NXCOMPAT) flag - meaning DEP is not enabled
-
Count unprotected PE filesExamine all PE files in the Quick Heal installation directory. Note how many files are missing either the ASLR (0x0140) or DEP (0x0100) flag, or both. The CVE references approximately 165 PE files being affected.Affected if A significant number of PE files (close to 165) are missing ASLR and/or DEP protection flags
If Quick Heal product version is 10.1.0.316 or lower AND multiple PE files in the installation directory lack both DYNAMICBASE (ASLR) and NXCOMPAT (DEP) flags in their headers, the environment is affected by CVE-2017-8776.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataThe vendor must rebuild all affected PE files with /DYNAMICBASE (ASLR) and /NXCOMPAT (DEP) linker flags, then re-release the software. Users should monitor for vendor updates and apply them promptly.
