Goldstein Lyor commented on SSHD-737:
-

I admit that I have not researched this in depth so I trust your judgment. 
However, since the fix seems a bit more complex than initially assumed let's 
make sure we do not introduce a bug. Can we use some real-life test case DSS 
keys, test data and signatures that we somehow know cause this problem - 
preferably for all the support key sizes (see {{BaseTestSupport#DSS_SIZES}})? 
(I admit I have not had time to think how this can be achieved, but 
nevertheless it seems to me that we should make the attempt). The 
{{DERWriterTest}} is fine, but we are using "synthetic" values that might not 
cover all the real-life conditions the code is likely to encounter.

Well, that's a good point you raised.  I did a few more tests on this method 
and found a problem.
In the current state, {{DERWriter#writeBigInteger}} and 
{{DERReader#readBigInteger}} do not work well.

For example, the following tests fail:
{code}
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class DERWriterTest extends BaseTestSupport {
public DERWriterTest() {
super();
}

@Test
public void testWriteStripLeadingZeroes() throws IOException {
doTestWriteRead(true);
}

@Test
public void testWriteNoStripLeadingZeroes() throws IOException {
doTestWriteRead(false);
}

private void doTestWriteRead(boolean strip) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
try (DERWriter w = new DERWriter(baos)) {
w.writeBigInteger(BigInteger.valueOf(-1));
w.writeBigInteger(BigInteger.valueOf(129));
w.writeBigInteger(new byte[] { 0, 0 }, 0, 2, strip);
w.writeBigInteger(new byte[] { 0, 1 }, 0, 2, strip);
}
} finally {
baos.close();
}

try (DERParser parser = new DERParser(baos.toByteArray())) {
assertEquals(BigInteger.valueOf(-1), parser.readBigInteger());
assertEquals(BigInteger.valueOf(129), parser.readBigInteger());
assertEquals(BigInteger.valueOf(0), parser.readBigInteger());
assertEquals(BigInteger.valueOf(1), parser.readBigInteger());
}
}

}
{code}

I think it may be better written this way:
{code}
public void writeBigInteger(byte[] bytes, int off, int len, boolean 
stripLeadingZeroes) throws IOException {
if (stripLeadingZeroes) {
while (len > 1 && bytes[off] == 0 && (bytes[off+1] == 0 || 
(bytes[off+1] & 0x80) == 0)) {
off++;
len--;
}
}
write(0x02);// indicate it is an INTEGER
writeLength(len);
write(bytes, off, len);
}
{code}

I have no problem with the fix, except I prefer we change the code as follows 
to avoid {{IndexOutOfBoundsException}} - as unlikely as it may be:
{code:java}
if (stripLeadingZeroes) {
   while ((len > 0) && (bytes[off] == 0)) {
   off++;
   len--;
   }
{code}

Our server uses SimpleGeneratorHostKeyProvider. We only have the binary 
key/pair file that is generates. Is that what u are asking for?
Can mention that this fault doesn't happen all the time, about 5% of the 
requests are failing with "redundant leading 0s".

[jira] [Commented] (SSHD-737) "Invalid encoding: redundant leading 0s" when establishing session

Goldstein Lyor commented on SSHD-737:
-

P.S. I remember we solve a similar issue for RSA keys and leading zeroes - see 
{{AbstractDH#stripLeadingZeroes}} that was introduced as part of SSHD-330 - 
perhaps something similar is required for DSA signature...

Can you provide a sample DSA key pair that reproduces this problem so we can 
investigate (and fix) more easily ?

[jira] [Commented] (SSHD-737) "Invalid encoding: redundant leading 0s" when establishing session

Thomas Davidsson commented on SSHD-737:

JDK/OpenJDK will not solve the problem, As i understand it they have corrected 
some parts in the security-libs 
(http://www.oracle.com/technetwork/java/javase/8u121-relnotes-3315208.html)
_More checks added to DER encoding parsing code
 More checks are added to the DER encoding parsing code to catch various 
encoding errors. In addition, signatures which contain constructed indefinite 
length encoding will now lead to IOException during parsing. Note that 
signatures generated using JDK default providers are not affected by this 
change. _
 JDK-8168714 (not public)

So this issue need to be solved in sshd-core lib.

[~lgoldstein] I remember this was just marked as "won't fix", because I 
reported it for very old version... But it started to fail on latest one too... 
I still think the bug isn't really solved on JDK/OpenJDK side...

Hi,
thanks for the fast response.
We are not using openjdk, we are using oracle jdk.
Our problem occurs when the server using DSA algorithm. Then  our client fails 
when connecting and the SignatureDSA.verify method is executed:

Hi,
With the lift to Java 1.8.0_144 and SSHD-CORE 1.6.0 the issue with "Invalid 
encoding: redundant leading 0s" has started to occur in our environment.
We found a bugfix for JSCH that solved the problem for us: 
https://github.com/Jurrie/jsch-111-bugfix
A description of the bugfix can be read in the discussion from Jurrie Overgoor: 
https://sourceforge.net/p/jsch/bugs/111/
Can this issue be reopened?

Thanks

Goldstein Lyor commented on SSHD-737:
-

Sorry, cannot remember - it was a long time ago + since then we added several 
improvements related to ciphers, keys and loading them from files. Please try 
the latest official release (1.4.0) and see if the problem persists. If so, can 
you attach the key(s) you are trying to use that cause this problem to the 
issue ...
