Description Laura Pardo 2018-07-13 21:01:28 UTC

A flaw was found in Legion of the Bouncy Castle Java Cryptography APIs version prior to 1.60. A lack of class checking in the deserialization of XMSS/XMSS^MT private keys with BDS state information can result in the execution of unexpected code.

Comment 1 Laura Pardo 2018-07-13 21:02:20 UTC

Created bouncycastle tracking bugs for this issue:

Affects: epel-all [bug 1601099]
Affects: fedora-all [bug 1601098]

Comment 2 Doran Moppert 2018-07-16 01:21:09 UTC

Statement:

The XMSS/XMSS^MT algorithms were first introduced in upstream bouncycastle version 1.57.  Versions prior to this, that have not had the new algorithms back-ported, are not affected.
