CVE-2017-8775
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 are vulnerable to Memory Corruption while parsing a malformed Mach-O file.
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) contain a memory corruption vulnerability when parsing malformed Mach-O files, the executable file format used by macOS. This could allow remote attackers to cause memory corruption leading to potential code execution or denial of service.

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.
-
Verify Quick Heal product is installedLook for Quick Heal application in Program Files or Program Files (x86), or check Add/Remove Programs for Quick Heal entriesAffected if Quick Heal security software is present on the system
-
Identify the specific Quick Heal productCheck the installed application name in Add/Remove Programs or the program directory for 'Quick Heal AntiVirus Pro', 'Quick Heal Internet Security', or 'Quick Heal Total Security'Affected if One of the three affected products is installed
-
Determine the installed versionCheck the version information of the Quick Heal installation via its About/Help menu, or look for version details in the program's main executable or installation directoryAffected if Version is 10.1.0.316 or lower
-
Confirm Mach-O file scanning capability is enabledVerify that real-time scanning or on-demand file scanning features are active, which would cause the product to parse executable files including Mach-O formatAffected if File scanning is enabled and the product processes Mach-O files
A system is affected if any Quick Heal AntiVirus Pro, Internet Security, or Total Security version 10.1.0.316 or lower is installed with scanning capabilities active.

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 dataUpdate Quick Heal security products to the latest version available from the vendor. Avoid opening or scanning untrusted Mach-O files from unknown sources until the patch is applied.
