A denial of service vulnerability exists in some motherboard implementations of Intel e1000e/82574L network controller devices through 2013-02-06 where the device can be brought into a non-processing state when parsing 32 hex, 33 hex, or 34 hex byte values at the 0x47f offset. NOTE: A followup statement from Intel suggests that the root cause of this issue was an incorrectly configured EEPROM image.
The software does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.
- 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.
