Name of the Vulnerable Software and Affected Versions

Description
The issue is a heap-based buffer overflow in the
Scanner::fill function located in parse/scanner.cc, which can be triggered by a long lexeme.Recommendations
For re2c version 1.3, consider restricting the input length to prevent the buffer overflow until a patch is available.
As a temporary workaround, avoid using long lexemes in the
Scanner::fill function to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability. Found an issue in the description? Have something to add? Feel free to write us 👾
