Details

A flaw was found in m17n-lib. An attacker who supplies crafted input to an application processing ISO-2022 encoded text can cause the library to read uninitialized memory from the stack. If the application exposes or returns the decoded output, this flaw can result in unexpected behavior and limited information disclosure.
