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 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.

Untrusted search path vulnerability in McAfee VirusScan Enterprise before 8.7i allows local users to gain privileges via a Trojan horse DLL in an unspecified directory, as demonstrated by scanning a document located on a remote share.

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

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.

Buffer overflow in the IsOldAppInstalled function in the McSubMgr.McSubMgr Subscription Manager ActiveX control (MCSUBMGR.DLL) in McAfee SecurityCenter before 6.0.25 and 7.x before 7.2.147 allows remote attackers to execute arbitrary code via a crafted argument.

Buffer overflow in the On-Access Scanner in McAfee VirusScan Enterprise before 8.0i Patch 12 allows user-assisted remote attackers to execute arbitrary code via a long filename containing multi-byte (Unicode) characters.

McAfee VirusScan Enterprise 8.5.0.i uses insecure permissions for certain Windows Registry keys, which allows local users to bypass local password protection via the UIP value in (1) HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DesktopProtection or (2) HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\TVD\VirusScan Entreprise\CurrentVersion. NOTE: this issue has been disputed by third-party researchers, stating that the default permissions for HKEY_LOCAL_MACHINE\SOFTWARE does not allow for write access and the product does not modify the inherited permissions. There might be an interaction error with another product

Untrusted search path vulnerability in McAfee VirusScan for Linux 4510e and earlier includes the current working directory in the DT_RPATH environment variable, which allows local users to load arbitrary ELF DSO libraries and execute arbitrary code by installing malicious libraries in that directory.

McAfee Network Agent (mcnasvc.exe) 1.0.178.0, as used by multiple McAfee products possibly including Internet Security Suite, Personal Firewall Plus, and VirusScan, allows remote attackers to cause a denial of service (agent crash) via a long packet, possibly because of an invalid string position field value. NOTE: some of these details are obtained from third party information.
