Module IncorrectIntegerConversionLib

Import path

import semmle.go.security.IncorrectIntegerConversionLib

Imports

go	Provides classes for working with Go programs.

Predicates

describeBitSize2	Gets a string describing the size of the integer parsed.
getIntTypeBitSize	Get the size of `int` or `uint` in `file`, or `architectureSpecificBitSize` if it is architecture-specific.
isSourceWithBitSize	Holds if `source` is the result of a call to `strconv.Atoi`, `strconv.ParseInt`, or `strconv.ParseUint`, `bitSize` is the `bitSize` argument to that call (or 0 for `strconv.Atoi`) and hence must be between 0 and 64, and `isSigned` is true for `strconv.Atoi`, true for `strconv.ParseInt` and false for `strconv.ParseUint`.

Classes

FlowState	Flow state for ConversionWithoutBoundsCheckConfig.
FlowStateTransformer	A node that blocks some flow states and transforms some others as they flow through it.
TypeAssertionCheck	An expression which a type assertion guarantees will have a particular integer type.
TypeSwitchVarFlowStateTransformer	The implicit definition of a variable with integer type for a case clause of a type switch statement which declares a variable in its guard, which has effectively had a checked type assertion.
UpperBoundCheck	A node that is safely guarded by an `UpperBoundCheckGuard`.
UpperBoundCheckGuard	An upper bound check that compares a variable to a constant value.

Aliases

Flow	Tracks taint flow from an integer obtained from parsing a string that flows to a type conversion to a smaller integer type, which could cause data loss.
