Security update for the Linux Kernel (Live Patch 23 for SLE 12 SP2)

This update for the Linux Kernel 4.4.121-92_85 fixes one issue.

The following security issue was 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 (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098).

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.
