Incorrect Permission Assignment for Critical Resource vulnerability in McAfee VirusScan Enterprise (VSE) prior to 8.8 Patch 16 allows local administrators to bypass local security protection through VSE not correctly integrating with Windows Defender Application Control via careful manipulation of the Code Integrity checks.

The Buffer Overflow Protection (BOP) feature in McAfee VirusScan Enterprise before 8.8 Patch 6 allocates memory with Read, Write, Execute (RWX) permissions at predictable addresses on 32-bit platforms when protecting another application, which allows attackers to bypass the DEP and ASLR protection mechanisms via unspecified vectors.

McAfee VirusScan Enterprise before 8.8 allows local users to disable the product by leveraging administrative privileges to execute an unspecified Metasploit Framework module.

McAfee VirusScan Enterprise 8.5i and 8.7i does not properly interact with the processing of hcp:// URLs by the Microsoft Help and Support Center, which makes it easier for remote attackers to execute arbitrary code via malware that is correctly detected by this product, but with a detection approach that occurs too late to stop the code execution.

The AV engine before DAT 5600 in McAfee VirusScan, Total Protection, Internet Security, SecurityShield for Microsoft ISA Server, Security for Microsoft Sharepoint, Security for Email Servers, Email Gateway, and Active Virus Defense allows remote attackers to bypass virus detection via (1) an invalid Headflags field in a malformed RAR archive, (2) an invalid Packsize field in a malformed RAR archive, or (3) an invalid Filelength field in a malformed ZIP archive.
