The x/text
package for Go has 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
.
