This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM. Robert Swiecki discovered that the Linux kernel did not properly apply Address Space Layout Randomization in some situations for setuid elf binaries. A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid elf binary. Various other issues were also addressed.
aa4cc845dcf7f973e16414a993cbab9ad894d59053308b8791cfaee4cab3ec45Ubuntu Security Notice 4008-2 - USN-4008-1 fixed multiple security issues in the Linux kernel. This update provides the corresponding changes to AppArmor policy for correctly operating under the Linux kernel with fixes for CVE-2019-11190. Without these changes, some profile transitions may be unintentionally denied due to missing mmap rules. Various other issues were also addressed.

A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid elf binary. It was discovered that a null pointer dereference vulnerability existed in the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

A local attacker could use this to cause a denial of service. It was discovered that a race condition leading to a use-after-free existed in the Reliable Datagram Sockets protocol implementation in the Linux kernel. The RDS protocol is blacklisted by default in Ubuntu. If enabled, a local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
