The NQ Mobile Security & Antivirus (aka com.nqmobile.antivirus20) application 7.2.16.00 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The AMC Security- Antivirus, Clean (aka com.iobit.mobilecare) application 4.4.1 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Stack-based buffer overflow in pepoly.dll in Quick Heal AntiVirus Pro 7.0.0.1 allows local users to execute arbitrary code or cause a denial of service (process crash) via a long *.text value in a PE file.

The TrustGo Antivirus & Mobile Security application before 1.3.6 for Android allows attackers to cause a denial of service (application crash) via a crafted application that sends an intent to com.trustgo.mobile.security.USSDScannerActivity with zero arguments.

The Lookout Mobile Security application before 8.17-8a39d3f for Android allows attackers to cause a denial of service (application crash) via a crafted application that sends an intent to com.lookout.security.ScanTell with zero arguments.

The Anti-theft service in AVG AntiVirus for Android allows physically proximate attackers to provide arbitrary location data via a "commonly available simple GPS location spoofer."

The decomposer engine in Symantec Endpoint Protection (SEP) 11.0, Symantec Endpoint Protection Small Business Edition 12.0, Symantec AntiVirus Corporate Edition (SAVCE) 10.x, and Symantec Scan Engine (SSE) before 5.2.8 does not properly perform bounds checks of the contents of CAB archives, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted file.

The Zoner AntiVirus Free application for Android does not verify that the server hostname matches a domain name in the subject's Common Name (CN) field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, as demonstrated by a server used for updating virus signature files.

Race condition in VIPRE Antivirus Premium 4.0.3272 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute

Symantec Norton AntiVirus 2011 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. NOTE: the researcher indicates that a vendor response was received, stating that this issue "falls into the work of our Firewall and not our AV (per our methodology of layers of defense)."
