CVE-2020-11668 SUSE Linux Enterprise Live Patching 15:kernel-livepatch-4_12_14-150_55-default-2-2.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2020/suse-su-20202525-1/ https://www.suse.com/security/cve/CVE-2020-11668.html CVE-2020-11668 https://bugzilla.suse.com/1168952 SUSE Bug 1168952 https://bugzilla.suse.com/1173942 SUSE Bug 1173942 A flaw was found in the Linux kernel’s implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. CVE-2020-14331 SUSE Linux Enterprise Live Patching 15:kernel-livepatch-4_12_14-150_55-default-2-2.2 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2020/suse-su-20202525-1/ https://www.suse.com/security/cve/CVE-2020-14331.html CVE-2020-14331 https://bugzilla.suse.com/1174205 SUSE Bug 1174205 https://bugzilla.suse.com/1174247 SUSE Bug 1174247 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.
