script_tag(name:"insight", value:"The openSUSE Leap 42.3 kernel was updated to 4.4.132 to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2018-3639: Information leaks using 'Memory Disambiguation' feature
in modern CPUs were mitigated, aka 'Spectre Variant 4' (bnc#1087082).
A new boot commandline option was introduced,
'spec_store_bypass_disable', which can have following values:
- auto: Kernel detects whether your CPU model contains an implementation
of Speculative Store Bypass and picks the most appropriate mitigation.
- on: disable Speculative Store Bypass
- off: enable Speculative Store Bypass
- prctl: Control Speculative Store Bypass per thread via prctl.
Speculative Store Bypass is enabled for a process by default. The
state of the control is inherited on fork.
- seccomp: Same as 'prctl' above, but all seccomp threads will disable
SSB unless they explicitly opt out.
The default is 'seccomp', meaning programs need explicit opt-in into the
mitigation.
Status can be queried via the
/sys/devices/system/cpu/vulnerabilities/spec_store_bypass file, containing:
- 'Vulnerable'
- 'Mitigation: Speculative Store Bypass disabled'
- 'Mitigation: Speculative Store Bypass disabled via prctl'
- 'Mitigation: Speculative Store Bypass disabled via prctl and seccomp'
- CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c allowed
local users to cause a denial of service (integer overflow and loop) via
crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP
ioctl. (bnc#1088241)
- CVE-2018-1130: Linux kernel was vulnerable to a null pointer dereference
in dccp_write_xmit() function in net/dccp/output.c in that allowed a
local user to cause a denial of service by a number of certain crafted
system calls (bnc#1092904).
- CVE-2018-5803: An error in the _sctp_make_chunk() function when handling
SCTP, packet length could have been exploited by a malicious local user
to cause a kernel crash and a DoS. (bnc#1083900).
- CVE-2018-1065: The netfilter subsystem mishandled the case of a rule
blob that contains a jump but lacks a user-defined chain, which allowed
local users to cause a denial of service (NULL pointer dereference) by
leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to
arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in
net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in
net/ipv6/netfilter/ip6_tables.c (bnc#1083650).
- CVE-2018-7492: A NULL pointer dereference was found in the
net/rds/rdma.c __rds_rdma_map() function that allowed local attackers to
