[PATCH 0/3] KEYS: Miscellaneous fixes

From: David Howells
Date: Sun Jul 17 2016 - 19:10:39 EST



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:
