4 years agoFix the heap corruption in libeay32!OBJ_add_object.
Gunnar Kudrjavets [Tue, 12 May 2015 22:44:45 +0000 (15:44 -0700)]
Fix the heap corruption in libeay32!OBJ_add_object.

Original 'sizeof(ADDED_OBJ)' was replaced with 'sizeof(*ao)'. However,
they return different sizes. Therefore as the result heap gets corrupted
and at some point later debug version of malloc() detects the corruption.

On x86 we can observe that as follows:

sizeof(*ao) == 4
sizeof(*ao[0]) == sizeof(ADDED_OBJ) == 8

Issue reproduces with either enabling CRT debug heap or Application
Verifier's full-page heap.

Basic debugging data from the moment the corruption is first detected:

Initialize potentially uninitialized local variables

Compiling OpenSSL code with MSVC and /W4 results in a number of warnings.
One category of warnings is particularly interesting - C4701 (potentially
uninitialized local variable 'name' used). This warning pretty much means
that there's a code path which results in uninitialized variables being used
or returned. Depending on compiler, its options, OS, values in registers
and/or stack, the results can be nondeterministic. Cases like this are very
hard to debug so it's rational to fix these issues.

This patch contains a set of trivial fixes for all the C4701 warnings (just
initializing variables to 0 or NULL or appropriate error code) to make sure
that deterministic values will be returned from all the execution paths.

Matt Caswell [Wed, 29 Apr 2015 12:22:18 +0000 (13:22 +0100)]
Fix buffer overrun in RSA signing

The problem occurs in EVP_PKEY_sign() when using RSA with X931 padding.
It is only triggered if the RSA key size is smaller than the digest length.
So with SHA512 you can trigger the overflow with anything less than an RSA
512 bit key. I managed to trigger a 62 byte overflow when using a 16 bit RSA
key. This wasn't sufficient to cause a crash, although your mileage may
vary.

In practice RSA keys of this length are never used and X931 padding is very
rare. Even if someone did use an excessively short RSA key, the chances of
them combining that with a longer digest and X931 padding is very
small. For these reasons I do not believe there is a security implication to
this. Thanks to Kevin Wojtysiak (Int3 Solutions) and Paramjot Oberoi (Int3
