Description

libuv before version 1.14.1, as bundled by Node.js before versions 16.4.1, 14.17.2 and 12.22.2, is vulnerable to an out-of-bounds read in the libuv's uv__idna_toascii() function which is used to convert strings to ASCII. This is called by Node's dns module's lookup() function and can lead to information disclosures or crashes.
