| | | | | | | | | | | * scd/app-openpgp.c (get_public_key): correctly close 'fp' upon use. -- Inside the get_public_key function, 'fp' was opened using popen, but incorrectly closed using fclose. Debian-Bug-Id: 773474

| | | | | | | | | | | | | * g10/keygen.c (generate_subkeypair): Release DEK soon. -- This fixes the out_of_core error in the test case of adding RSA-4096 subkey to RSA-4096 primary key with configuration: s2k-cipher-algo S10 Debian-bug-id: 772780
* gpg: Fix use of uninit.value in listing sig subpkts.Werner Koch2014-11-241-2/+7
| | | | | | | | | | | | | | | * g10/parse-packet.c (dump_sig_subpkt): Print regex subpacket sanitized. -- We may not use "%s" to print an arbitrary buffer. At least "%.*s" should have been used. However, it is in general preferable to escape control characters while printf user data.

* gpg: Make the use of "--verify FILE" for detached sigs harder.Werner Koch2014-11-144-38/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * g10/openfile.c (open_sigfile): Factor some code out to ... (get_matching_datafile): new function. * g10/plaintext.c (hash_datafiles): Do not try to find matching file in batch mode. * g10/mainproc.c (check_sig_and_print): Print a warning if a possibly matching data file is not used by a standard signatures. -- Allowing to use the abbreviated form for detached signatures is a long standing bug which has only been noticed by the public with the release of 2.1.0. :-( What we do is to remove the ability to check detached signature in --batch using the one file abbreviated mode. This should exhibit problems in scripts which use this insecure practice. We also print a warning if a matching data file exists but was not considered because the detached signature was actually a standard signature: gpgv: Good signature from "Werner Koch (dist sig)" gpgv: WARNING: not a detached signature; \ file 'gnupg-2.1.0.tar.bz2' was NOT verified! We can only print a warning because it is possible that a standard signature is indeed to be verified but by coincidence a file with a matching name is stored alongside the standard signature.

* gpg: Add build and runtime support for larger RSA keysDaniel Kahn Gillmor2014-10-033-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac: Added --enable-large-secmem option. * g10/options.h: Add opt.flags.large_rsa. * g10/gpg.c: Contingent on configure option: adjust secmem size, add gpg --enable-large-rsa, bound to opt.flags.large_rsa. * g10/keygen.c: Adjust max RSA size based on opt.flags.large_rsa * doc/gpg.texi: Document --enable-large-rsa. -- Some older implementations built and used RSA keys up to 16Kib, but the larger secret keys now fail when used by more recent GnuPG, due to secure memory limitations. Building with ./configure --enable-large-secmem will make gpg capable of working with those secret keys, as well as permitting the use of a new gpg option --enable-large-rsa, which let gpg generate RSA keys up to 8Kib when used with --batch --gen-key.

* Limit keysize for unattended key generation to useful values.Werner Koch2014-06-301-2/+10
| | | | | | | | | | | | * g10/keygen.c (gen_elg): Enforce keysize 1024 to 4096. (gen_rsa): Enforce keysize 1024 to 4096. (gen_dsa): Enforce keysize 768 to 3072. -- It was possible to create 16k RSA keys in batch mode. In addition to the silliness of such keys, they have the major drawback that GnuPG, with its limited amount of specially secured memory areas, the use of such keys may lead to an "out of secure memory" condition.
* Make screening of keyserver result work with multi-key commands.Werner Koch2014-06-301-23/+45
| | | | | | | | | | | | | | * g10/keyserver.c (ks_retrieval_filter_arg_s): new. (keyserver_retrieval_filter): Use new struct and check all descriptions. (keyserver_spawn): Pass filter arg suing the new struct. -- This is a fix for commit 52303043. The old code did only work for a single key. It failed as soon as several keys are specified ("gpg --refresh-keys" or "gpg --recv-key A B C").

(import_secret_one): Ditto. (import_keys_internal): Ditto. (import_keys_stream): Ditto. * g10/keyserver.c (keyserver_retrieval_filter): New. (keyserver_spawn): Pass filter to import_keys_stream() -- These changes introduces import functions that apply a constraining filter to imported keys. These filters can verify the fingerprints of the keys returned before importing them into the keyring, ensuring that the keys fetched from the keyserver are in fact those selected by the user beforehand.

* Print hash algorithm in sig recordsWerner Koch2014-06-231-6/+2
| | | | | | | | | | | * g10/keylist.c (list_keyblock_colon): Print field 16. -- We have this info already in gnupg-2 and it is easy to add it to 1.4. Debian-bug-id: 672658 Patch written and tested by Daniel Leidert. See above.
* Remove useless diagnostic in MDC verification.Werner Koch2014-06-231-6/+4
| | | | | | | | | * g10/encr-data.c (decrypt_data): Do not distinguish between a bad MDC packet header and a bad MDC. -- The separate diagnostic was introduced for debugging a problems. For explaining an MDC error a single error message is easier to understand.

| | | | | | | | | | | | | * g10/apdu.c (pcsc_dword_t): New. It was named as DWORD (double-word) when a word was 16-bit. (struct reader_table_s): Fixes for types. (struct pcsc_readerstate_s) [__APPLE__]: Enable #pragma pack(1). Throughout: Fixes for types. -- GnuPG-bug-id: 1358 This is a backport of commit ae22d629b6028aa994ff09f012e1cb029575eeae.
* gpg: Use more specific reason codes for INV_RECP.Werner Koch2014-06-231-5/+13
| | | | | | | | | | * g10/pkclist.c (build_pk_list): Use more specific reasons codes for INV_RECP. -- GnuPG-bug-id: 1650 Note that this patch is a bit more limited than the one in 2.1.
* gpg: Avoid infinite loop in uncompressing garbled packets.Werner Koch2014-06-201-9/+12
| | | | | | | | | | | | | | | * g10/compress.c (do_uncompress): Limit the number of extra FF bytes. -- A packet like (a3 01 5b ff) leads to an infinite loop. Using --max-output won't help if it is a partial packet. This patch actually fixes a regression introduced on 1999-05-31 (c34c6769). Actually it would be sufficient to stuff just one extra 0xff byte. Given that this problem popped up only after 15 years, I feel safer to allow for a very few FF bytes. Thanks to Olivier Levillain and Florian Maury for their detailed report.
* gpg: Need to init the trustdb for import.Werner Koch2014-03-061-0/+1
| | | | | | | | | | * g10/trustdb.c (clear_ownertrusts): Init trustdb. -- This is actually a hack to fix a bug introduced with commit 2528178. Debian uses it and thus we should do too. GnuPG-bug-id: 1622
* Change --show-session-key to print the session key earlier.Werner Koch2013-12-112-10/+11
| | | | | | | | | | | | | | | | | | | | * g10/mainproc.c (proc_encrypted): Move show_session_key code to ... * g10/decrypt-data.c (decrypt_data): here. -- This feature can be used to return the session key for just a part of a file. For example to downloading just the first 32k of a huge file, decrypting that incomplete part and while ignoring all the errors break out the session key. The session key may then be used on the server to decrypt the entire file without the need to have the private key on the server. This is the same feature as commit 101a54add351ff62793cbfbf3877787c4791f833 for 2.1 and commit 3ae90ff28c500967cb90b1176299d2ca01ef450f for 2.0.

* Use blinding for the RSA secret operation.Werner Koch2013-12-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * cipher/random.c (randomize_mpi): New. * g10/gpgv.c (randomize_mpi): New stub. * cipher/rsa.c (USE_BLINDING): Define macro. (secret): Implement blinding. -- GPG 1.x has never used any protection against timing attacks on the RSA secret operation. The rationale for this has been that there was no way to mount a remote timing attack on GnuPG. With the turning up of Acoustic Cryptanalysis (http://cs.tau.ac.il/~tromer/acoustic) this assumption no longer holds true and thus we need to do do something about it. Blinding seems to be a suitable mitigation to the threat of key extraction. It does not help against distinguishing used keys, though. Note that GPG 2.x uses Libgcrypt which does blinding by default. The performance penalty is negligible: Modifying the core pubkey_sign or pubkey_decrypt function to run 100 times in a loop, the entire execution times for signing or decrypting a small message using a 4K RSA key on a Thinkpad X220 are Without blinding: 5.2s (8.9s) With blinding: 5.6s (9.3s) The numbers in parentheses give the values without the recently implemented k-ary exponentiation code. Thus for the next release the user will actually experience faster signing and decryption. A drawback of blinding is that we need random numbers even for decryption (albeit at low quality).
