An update that fixes 5 vulnerabilities is now available.

Description:

This update for the Linux Kernel 4.4.121-92_149 fixes several issues.

The following security issues were fixed:

- CVE-2020-27786: Fixed a potential user after free which could have led
to memory corruption or privilege escalation (bsc#1179616).
- CVE-2020-28374: Fixed insufficient identifier checking in the LIO SCSI
target code which could have been used by remote attackers to read or
write files via directory traversal in an XCOPY request (bsc#1178684).
- CVE-2020-25645: Fixed an issue where the traffic between two Geneve
endpoints may have been unencrypted when IPsec was 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 potential memory corruption due to a use after
free which could have led local escalation of privilege with System
execution privileges needed (bsc#1176931).
- CVE-2020-1749: Fixed an issue in some networking protocols in IPsec,
such as VXLAN and GENEVE tunnels over IPv6 where the kernel was not
correctly routing tunneled data over the encrypted link rather sending
the data unencrypted (bsc#1165631).
