Security update for the Linux Kernel (Live Patch 35 for SLE 12 SP3)

This update for the Linux Kernel 4.4.180-94_130 fixes several issues.

The following security issues were fixed:

  • CVE-2020-25668: Fixed a concurrency use-after-free in con_font_op (bsc#1178622).
  • CVE-2020-8694: Fixed an insufficient access control in the Linux kernel driver for some Intel(R) Processors which might have allowed an authenticated user to potentially enable information disclosure via local access (bsc#1178700).
  • CVE-2020-25705: Fixed a flaw which could have allowed an off-path remote user to effectively bypass source port UDP randomization (bsc#1178783).

A flaw was found in Linux Kernel because access to the global variable fg_console is not properly synchronized leading to a use after free in con_font_op.

Описание

A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that relies on UDP source port randomization are indirectly affected as well on the Linux Based Products (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4, SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All versions, SIMATIC NET CP 1243-1 (incl.

Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
