Node.js v4.3.2 Release Brief
v4.3.2 contains only one commit, an upgrade to OpenSSL 1.0.2g (up from 1.0.2h).
This is a low-impact security release, as we do not believe the issues from OpenSSL, as outlined below, are readily exploitable in Node.js.
- openssl: Upgrade from 1.0.2f to 1.0.2g (Ben Noordhuis) #5507
- Fix a double-free defect in parsing malformed DSA keys that may potentially be used for DoS or memory corruption attacks. It is likely to be very difficult to use this defect for a practical attack and is therefore considered low severity for Node.js users. More info is available at CVE-2016-0705.
- Fix a defect that can cause memory corruption in certain very rare cases relating to the internal
BN_dec2bn()functions. It is believed that Node.js is not invoking the code paths that use these functions so practical attacks via Node.js using this defect are unlikely to be possible. More info is available at CVE-2016-0797.
- Fix a defect that makes the CacheBleed Attack possible. This defect enables attackers to execute side-channel attacks leading to the potential recovery of entire RSA private keys. It only affects the Intel Sandy Bridge (and possibly older) microarchitecture when using hyper-threading. Newer microarchitectures, including Haswell, are unaffected. More info is available at CVE-2016-0702.

Do note that while we assess the security issues as being low-impact to Node.js, we still suggest you upgrade so as to avoid anything unforeseen.
