SUSE: 2020:3507-1 Important: Linux Kernel Security Issues and Fixes

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-25705: A flaw in the way reply ICMP packets are limited in was found that allowed to quickly scan open UDP ports. This flaw allowed an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software and services that rely on UDP source port randomization (like DNS) are indirectly affected as well. Kernel versions may be vulnerable to this issue (bsc#1175721, bsc#1178782). - CVE-2020-25704: Fixed a memory leak in perf_event_parse_addr_filter() (bsc#1178393). - CVE-2020-25668: Fixed a use-after-free in con_font_op() (bnc#1178123).
