glibc: glibc: Information disclosure or denial of service via ungetwc function with specific wide character encodings

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...
