Hi,

The following vulnerability was published for golang-x-text and
golang-golang-x-text.

CVE-2020-14040[0]:
| Go version v0.3.3 of the x/text package fixes a vulnerability in
| encoding/unicode that could lead to the UTF-16 decoder entering an
| infinite loop, causing the program to crash or run out of memory. An
| attacker could provide a single byte to a UTF16 decoder instantiated
| with UseBOM or ExpectBOM to trigger an infinite loop if the String
| function on the Decoder is called, or the Decoder is passed to
| golang.org/x/text/transform.String.
