This update for the Linux Kernel 4.4.103-92_56 fixes several issues. The following security issues were fixed: - CVE-2018-5391: Fixed a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may have caused a denial of service condition by sending specially crafted IP fragments. The current vulnerability became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size . - CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ .
