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.
