FIXED_BYProblem

buffer overflow vulnerability in wget v1.20.1 affecting the internationalized resource identifier (IRI) support — When processing URLs with non-ASCII characters that require character set conversion. Tension: wget's do_conversion() function in src/iri.c incorrectly manages the output buffer size during reallocation, allowing iconv() to write beyond allocated memory. Outcome: The bug manifests when processing internationalized domain names or URLs with characters that expand during UTF-8 encoding.
