+Advisory 
+********
+
+We recommend all developers upgrade to this v1.4 release, which addresses these security
+issues discovered in earlier releases:
+
+AP Trampoline Is Accessible to Service VM
+   This vulnerability is triggered when validating the memory isolation between
+   VM and hypervisor. AP Trampoline code exists in LOW_RAM region in hypervisor but is
+   potentially accessible to service VM. This could be used by an attacker to mount DoS
+   attacks on the hypervisor if service VM is compromised.
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
+
+Improper Usage Of ``LIST_FOREACH()`` macro
+   Testing discovered that the MACRO ``LIST_FOREACH()`` was incorrectly used for some cases
+   which may induce a "wild pointer" and cause ACRN Device Model crash. An attacker
+   could use this issue to cause a denial of service (DoS). 
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
+
+Hypervisor Crashed When Fuzzing HC_SET_CALLBACK_VECTOR
+   This vulnerability was reported by Fuzzing tool for debug version of ACRN. When software fails
+   to validate input properly, an attacker is able to craft the input in a form that is
+   not expected by the rest of the application. This can lead to parts of the system
+   receiving unintended input, which may result in altered control flow, arbitrary control
+   of a resource, or arbitrary code execution.
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
+
+FILE Pointer Is Not Closed After Using
+   This vulnerability was reported by Fuzzing tool. Leaving the file unclosed will cause
+   leaking file descriptor and may cause unexpected errors in Device Model program.
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
+
+Descriptor of Directory Stream Is Referenced After Release
+   This vulnerability was reported by Fuzzing tool. A successful call to ``closedir(DIR *dirp)``
+   also closes the underlying file descriptor associated with ``dirp``. Access to the released
+   descriptor may point to some arbitrary memory location or cause undefined behavior.
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
+
+Mutex Is Potentially Kept in Locked State Forever
+   This vulnerability was reported by Fuzzing tool. pthread_mutex_lock/unlock pairing was not
+   always done. Leaving a mutex in a locked state forever can cause program deadlock,
+   depending on the usage scenario.
+
+   | **Affected Release:** v1.3 and earlier.
+   | It’s recommended to upgrade ACRN to release v1.4
