* coding: prevented an unsigned to signed conversionNikos Mavrogiannopoulos2016-04-201-1/+1

* _asn1_expand_object_id: addressed crash when no value is present is nodeNikos Mavrogiannopoulos2016-04-081-0/+3
| | | | | | | With a specially crafted ASN.1 description _asn1_expand_object_id, passes a null pointer as p4->value to the function _asn1_str_cat, which expects a pointer to a string. This patch addresses the issue. Reported by Pascal Cuoq.
* decoding: removed redundant functionsNikos Mavrogiannopoulos2016-04-081-223/+150
| | | | | Simplified the STRING BER decoding by using asn1_decode_simple_ber(). This removes complex duplicate code.
* asn1_decode_simple_ber: simplified and cleaned upNikos Mavrogiannopoulos2016-04-082-45/+73

* _asn1_extract_der_octet: properly account the bytes read through indefinite ↵Nikos Mavrogiannopoulos2016-04-061-4/+8
| | | | | | | encodings This prevents infinite recursions in the function loop. Reported by Pascal Cuoq.
* libtasn1.h: updated for 4.8Nikos Mavrogiannopoulos2016-04-041-1/+1
|
* _asn1_extract_der_octet: catch invalid input cases earlyNikos Mavrogiannopoulos2016-04-041-1/+8
| | | | | | That is, check the calculated lengths for validity prior to entering a loop. This avoids an infinite recursion. Reported by Pascal Cuoq.
* Simplify _asn1_append_value() and avoid memcpy's with zero lengthNikos Mavrogiannopoulos2016-04-041-9/+19
| | | | Based on patch of Pascal Cuoq <pascal.cuoq@trust-in-soft.com>
* use a safer variant of reallocNikos Mavrogiannopoulos2016-04-043-4/+20
| | | | | This variant does not create memory leaks if allocation fails. Report and initial patch by Pascal Cuoq.
* decoding: improved tail cache in _asn1_append_sequence_setNikos Mavrogiannopoulos2016-04-043-16/+27
| | | | | We keep the head node in addition to the tail information to allow easier deduction of the validity of the cache.
* fixed incorrect parameter to _asn1_append_sequence_set()Nikos Mavrogiannopoulos2016-04-031-1/+1
| | | | | This was uncovered by the previous revert, and seemed working due to the optimization semantics.
* Revert "optimized _asn1_find_up()."Nikos Mavrogiannopoulos2016-04-037-51/+38
| | | | | | | This reverts commit 4010bb04588fca86a9f6d683b637c05b4cec24e0. This optimization did not offer much benefit and there may be corner cases in the internal structure handling that may not be possibly to handle with this optimization.
