get_ext() does not check the return value of the various mbedtls_*
functions, as cert_parse() is assumed to have guaranteed that they will
always succeed. However, it passes the end of an extension as the end
pointer to these functions, whereas cert_parse() passes the end of the
TBSCertificate. Furthermore, cert_parse() does *not* check that the
contents of the extension have the same length as the extension itself.
Before fd37982a19a4a291 ("fix(auth): forbid junk after extensions"),
cert_parse() also does not check that the extension block extends to the
end of the TBSCertificate.
This is a problem, as mbedtls_asn1_get_tag() leaves *p and *len
undefined on failure. In practice, this results in get_ext() continuing
to parse at different offsets than were used (and validated) by
cert_parse(), which means that the in-bounds guarantee provided by
cert_parse() no longer holds.
This patch fixes the remaining flaw by enforcing that the contents of an
extension are the same length as the extension itself.

auth_nvctr() does not check that the buffer provided is long enough to
hold an ASN.1 INTEGER, or even that the buffer is non-empty. Since
auth_nvctr() will only ever read 6 bytes, it is possible to read up to
6 bytes past the end of the buffer.
This out-of-bounds read turns out to be harmless. The only caller of
auth_nvctr() always passes a pointer into an X.509 TBSCertificate, and
all in-tree chains of trust require that the certificate’s signature has
already been validated. This means that the signature algorithm
identifier is at least 4 bytes and the signature itself more than that.
Therefore, the data read will be from the certificate itself. Even if
the certificate signature has not been validated, an out-of-bounds read
is still not possible. Since there are at least two bytes (tag and
length) in both the signature algorithm ID and the signature itself, an
out-of-bounds read would require that the tag byte of the signature
algorithm ID would need to be either the tag or length byte of the
DER-encoded nonvolatile counter. However, this byte must be
(MBEDTLS_ASN1_CONSTRUCTED | MBEDTLS_ASN1_SEQUENCE) (0x30), which is
greater than 4 and not equal to MBEDTLS_ASN1_INTEGER (2). Therefore,
auth_nvctr() will error out before reading the integer itself,
preventing an out-of-bounds read.
