Security update for the Linux Kernel (Live Patch 38 for SLE 12 SP2)

This update for the Linux Kernel 4.4.121-92_146 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-2020-25645: Fixed an issue which traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted (bsc#1177513).
  • CVE-2020-0429: Fixed a memory corruption due to a use after free which could have led to to local privilege escalation (bsc#1176931).
  • CVE-2020-11668: Fixed an issue where the Xirlink camera USB driver mishandled invalid descriptors (bsc#1173942).
  • CVE-2020-1749: Use ip6_dst_lookup_flow instead of ip6_dst_lookup (bsc#1165631).

In l2tp_session_delete and related functions of l2tp_core.c, there is possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges needed.

Описание

In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770.

Описание

A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.

Описание

A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.

Описание

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.
