CVE-2019-1039

An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.To exploit this vulnerability, an authenticated attacker could run a specially crafted application, aka Windows Kernel Information Disclosure Vulnerability.

Weakness 

The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

Affected Software 

Potential Mitigations 

• Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
• For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable’s type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
