    Summary: golang.org/x/text Infinite loop

    Details: 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. ### Specific Go Packages Affected golang.org/x/text/encoding/unicode golang.org/x/text/transform
