Mojang confirms it has fixed Minecraft Vulnerabilities

Mojang, the company behind the popular Minecraft game has announced that it has fixed a security issue which exploited a loophole causing the game servers to crash. A security researcher by name Ammar Askar observed that the exploit allows any attacker to send malformed packets that causes servers to crash by exhausting its memory. The response from the game creator – Mojang was unsatisfactory. Despite the vulnerability was responsibly and privately disclosed to the Minecraft team, there were no actions taken by the company – which made the researcher to make the exploit public.


Minecraft Vulnerabilities fixed

Mojang wrote in its blog that it has released a new version of Minecraft 1.8, called 1.8.4, is now available for download in the launcher. This particular release by Mojang fixes some of the reported security issues, in addition to minor bug fixes and related performance tweaks.

The updated version  is fully compatible with previous 1.8 versions and Mojang recommends that it is still highly recommended to update to 1.8.4 as soon as possible.

Nathan Adams, one of the Mojang Team members tweeted,

That exploit posted last night is fixed in 1.8.4, but so are other (arguably worse) exploits. Be sure to update!
