An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.4.121-92_104 fixes several issues.
The following security issues were fixed:
o CVE-2019-11477: Jonathan Looney discovered that the TCP_SKB_CB(skb)->
tcp_gso_segs value was subject to an integer overflow when handling TCP
Selective Acknowledgments (SACKs). A remote attacker could use this to
cause a denial of service. (bsc#1137586)
o CVE-2019-11478: Jonathan Looney discovered that the TCP retransmission
queue implementation in tcp_fragment could be fragmented when handling
certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker
could use this to cause a denial of service. (bsc#1137586)
o CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
possibly escalate privileges was found in the mwifiex kernel module while
connecting to a malicious wireless network (bsc#1136424).
This update contains a regression fix for CVE-2019-11477 and CVE-2019-11478
(bsc#1140747).
