______________________________________________________________________________
An update that solves three vulnerabilities and has 17
fixes is now available.
Description:
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).
