After a realloc (realloc is also used for initial alloc) the allocated
size if the buffer is not correctly recorded. Thus an overflow can be
introduced by receiving data with different line lengths in a specific
order. This is not easy exploitable because libassuan constructs the
line. However a crash has been reported and thus it might be possible
to constructs an exploit.
CVE-id: CVE-2014-3564
Reported-by: Tomáš Trnka
* src/gpgme.h.in (GPGME_KEYLIST_MODE_WITH_SECRET): New.
* src/engine-gpg.c (gpg_keylist_build_options): Handle new mode.
* src/engine-gpgsm.c (gpgsm_keylist, gpgsm_keylist_ext): Ditto.
* src/keylist.c (parse_sec_field15): Add arg key and take care of
--with-secret output.
* src/gpgme-tool.c (gt_get_keylist_mode, cmd_keylist_mode): Add
"with_secret". Print card info and and secret flag for subkeys.

engine info after freeing.
--
The engine hack is useful in case the other release functions
accidently call engine release.
* configure.ac (NEED_GPG_VERSION, NEED_GPGSM_VERSION)
(NEED_G13_VERSION, NEED_GPGCONF_VERSION): Remove vars and all related
checks. Do not check for any engine version.

(struct dirinfo): Add field gpgconf_name.
(_gpgme_get_default_gpgconf_name): Use WANT_GPGCONF_NAME.
(get_gpgconf_item): Set gpgconf name and adjust for _gpgme_get_*_path
now returning a malloced string.

uiserver.

string.
* src/engine-g13.c (g13_get_req_version): Use a hardwired string with
the required version. This info belongs into this file.

* src/engine-gpgconf.c (gpgconf_get_req_version): Ditto.
* src/engine-gpgsm.c (gpgsm_get_req_version): Ditto.
* tests/t-engine-info.c: Replace now useless test by an info output.
* tests/gpg/Makefile.am (GPG, GPG_AGENT): Hardwire gpg and gpg-agent.

(hlp_passwd): Move close to cmd_passwd.
--
It is often useful to have a way to identify the data which needs
processing. This is such a common task that it makes sense to
implement this in gpgme to avoid diverging implementations.
* src/util.h: Move some prototypes to ...
* src/sys-util.h: New.
* src/Makefile.am (main_sources): Add sys-util.h.
* configure.ac (AH_VERBATIM): Add DIRSEP_C and DIRSEP_S.

(WANT_GPG_NAME, WANT_GPGSM_NAME, WANT_G13_NAME)
(WANT_UISRV_SOCKET): New.
(dirinfo): Add corresponding fields.
(parse_output): Add arg COMPONENTS and set new fields.
(read_gpgconf_dirs): Add arg components and act upon it.
(get_gpgconf_item): Call read_gpgconf_dirs two times. Add debug
output.

--
The default engines names are now taken from the output of gpgconf.
If gpgconf is not installed gpg 1 is assumed and locate the same was
as gpgconf.
* configure.ac (NEED__FILE_OFFSET_BITS): Change to define gpgme_off_t
and gpgme_ssize_t.
(API__OFF_T, API__SSIZE_T): New ac_subst.

(_gpgme_engine_ops_gpg): Register gpg_set_pinentry_mode.
--
Note that this new fucntion may only be used with gpg 2.1.

(_gpgme_debug_set_debug_envvar): New.
(debug_init): Take ENVVAR_OVERRIDE in account.
--
On Android envvars can't be used, thus we need another way to enable
GPGME debugging. The new function allows this and may be used in the
future to implement similar things.
* src/verify.c (gpgme_op_verify_result): Update summary field.
--
This is actually a hack to solve the problem that GPGME currently does
not emit ERRSIG for a missing public key.

* libgpgme.vers: Likewise.

gpgme_error_t.
(gpgme_err_code_from_syserror, gpgme_err_set_errno): New prototype.
(gpgme_error_from_syserror): New inline function (why are
gpgme_err_make_from_errno and gpgme_error_from_errno not inline
functions?).
* error.c (gpgme_error_from_errno): Fix return type to gpgme_error_t.
(gpgme_err_set_errno, gpgme_err_code_from_syserror): New functions.
