In _asn1_tag_der(), the first while loop for the long form may end up with a "k" value with "ASN1_MAX_TAG_SIZE" and cause the buffer overrun in the second while loop. This commit tweaks the conditional check to avoid producing a too large "k". This is a quick fix and may differ from the official upstream fix. libtasn1 issue: https://gitlab.com/gnutls/libtasn1/-/issues/49 Signed-off-by: Gary Lin <glin@suse.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com> Tested-by: Stefan Berger <stefanb@linux.ibm.com>
