Insufficient initialization in Intel(R) SGX SDK Windows versions 2.4.100.51291 and earlier, and Linux versions 2.6.100.51363 and earlier, may allow an authenticated user to enable information disclosure, escalation of privilege or denial of service via local access.

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

Name Vendor Start Version End Version
Software_guard_extensions_sdk Intel 2.3.100.49777 2.3.100.49777
Software_guard_extensions_sdk Intel 2.3.101.50222 2.3.101.50222
Software_guard_extensions_sdk Intel 2.4.100.51291 2.4.100.51291

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.
