Ubuntu Security Notice 6385-1 - It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service.
397aabee4166381c7e45af794aab5e2f5ce22baf3c0ee09c03c9b743ea1a8b5fIt was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform data buffer size validation in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service (system crash) or possibly expose sensitive information. Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service (guest crash). Various other issues were also addressed.

2ed9de86da2c1e7cc0b4f8970c86b427aa7bf63dcea72f209cebdcce6cd60b19This tool packs up to 4KB of compressed shellcode into an executable binary, near-instantly. The output file will always have the same MD5 hash: 3cebbe60d91ce760409bbe513593e401. Currently, only Linux x86-64 is supported. It would be trivial to port this technique to other platforms, although each version would end up with a different MD5.

This a bind tcp shellcode that open a listen socket on 0.0.0.0 and port 1337. In order to accomplish this task the shellcode uses the PEB method to locate the baseAddress of the required module and the Export Directory Table to locate symbols. Also the shellcode uses a hash function to gather dynamically the required symbols without worry about the length.
