Hi James,
Here are three miscellaneous fixes:
(1) Fix a panic in some debugging code in PKCS#7. This can only happen by
explicitly inserting a #define DEBUG into the code.
(2) Fix the calculation of the digest length in the PE file parser. This
causes a failure where there should be a success.
(3) Fix the case where an X.509 cert can be added as an asymmetric key to
a trusted keyring with no trust restriction if no AKID is supplied.
Bugs (1) and (2) aren't particularly problematic, but (3) allows a security
check to be bypassed. Bug (3) is added since the 4.6 kernel.
The patches can be found here also:
