[gnutls-dev] [PATCH 1/1] crt_get_issuer_dn and friends request the wrong sized buffer

[Adam Langley]

With GnuTLS 1.2.[34] calling gnutls_x509_crt_get_issuer_dn with a NULL
parameter will cause the function to request (by filling out the int
*size argument) a buffer which is one byte too small. Calling the
function again with a buffer of the requested size will fail.

When a larger buffer is provided, the returned size is one byte too
large as it includes the NUL terminator which seems to be counter to
the convention in GnuTLS.
