The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed :
CVE-2020-12351: Fixed a type confusion while processing AMP packets aka ‘BleedingTooth’ aka ‘BadKarma’ (bsc#1177724).
CVE-2020-12352: Fixed an information leak when processing certain AMP packets aka ‘BleedingTooth’ aka ‘BadChoice’ (bsc#1177725).
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#1177511).
The update package also includes non-security fixes. See advisory for details.
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
