Section 4.3 Vectors says:

The length of
   an encoded vector must be an even multiple of the length of a single
   element (for example, a 17-byte vector of uint16 would be illegal).

It should say:

The length of
   an encoded vector must be a whole multiple of the length of a single
   element (for example, a 17-byte vector of uint16 would be illegal).

Notes:

Original text implies vectors can only contain even (0,2,4,6,8...) numbers of elements. The example does not resolve this but indicates the intent is that parts of elements are not allowed. It is clear from other examples that odd numbers of elements are permitted.

Paul Wouters (AD): As TLS 1.2 is obsoleted by TLS 1.3, this errata is closed as Verified. In TLS 1.3 in RFC 8447 the text states more clearly: Here, T' occupies n bytes in the data stream, where n is a multiple of the size of T.
