Incorrect conversion between integer types

Incorrect conversion of an integer with architecture-dependent bit size from [strconv.Atoi](1) to a lower bit size type uint8 without an upper bound check. Incorrect conversion of an integer with architecture-dependent bit size from [strconv.Atoi](1) to a lower bit size type uint8 without an upper bound check.

Copilot Autofix AI 17 days ago

To fix the problem, we need to ensure that the integer value parsed from the string is within the valid range for a byte (0-255) before performing the conversion. This can be done by adding a bounds check after parsing the integer and before converting it to a byte.

  1. Parse the integer using strconv.Atoi.
  2. Check if the parsed integer is within the range of 0 to 255.
  3. If the integer is within the valid range, convert it to a byte.
  4. If the integer is outside the valid range, handle the error appropriately (e.g., skip the conversion or use a default value).

Incorrect conversion between integer types

Incorrect conversion of a signed 32-bit integer from [strconv.ParseInt](1) to a lower bit size type uint8 without an upper bound check.

Copilot Autofix AI 17 days ago

To fix the problem, we need to ensure that the parsed integer value is within the valid range for a byte (0 to 255) before performing the conversion. This can be done by adding a bounds check after parsing the integer and before converting it to a byte.

  • We will add a check to ensure that the parsed integer is within the range of 0 to 255.
  • If the parsed integer is outside this range, we will skip the conversion and continue with the next match.
  • This change will be made in the decodeHtmlHex function in the file pkg/decoders/html_entity.go.
