script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 kernel version 3.12.74 was updated to receive various security and bugfixes.
The following security bugs were fixed:
CVE-2019-11477: A sequence of SACKs may have been crafted by a remote
attacker such that one can trigger an integer overflow, leading to a
kernel panic. (bsc#1137586).
CVE-2019-11478: It is possible to send a crafted sequence of SACKs which
will fragment the TCP retransmission queue. A remote attacker may be
able to further exploit the fragmented queue to cause an expensive
linked-list walk for subsequent SACKs received for that same TCP
connection.
CVE-2019-11479: It was possible to send a crafted sequence of SACKs
which will fragment the RACK send map. A remote attacker may be able to
further exploit the fragmented send map to cause an expensive
linked-list walk for subsequent SACKs received for that same TCP
connection. This would have resulted in excess resource consumption due
to low mss values.
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. (bnc#1136424)
CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux
kernel allowed local attackers to observe page cache access patterns of
other processes on the same system, potentially allowing sniffing of
secret information. (Fixing this affects the output of the fincore
program.) Limited remote exploitation may be possible, as demonstrated
by latency differences in accessing public files from an Apache HTTP
Server. (bnc#1120843)
CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out
the unused memory region in the extent tree block, which might allow
local users to obtain sensitive information by reading uninitialized
data in the filesystem. (bnc#1135281)
CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on
setuid programs (such as /bin/su) because install_exec_creds() is called
too late in load_elf_binary() in fs/binfmt_elf.c, and thus the
ptrace_may_access() check has a race condition when reading
/proc/pid/stat. (bnc#1131543)
CVE-2019-11884: The do_hidp_sock_ioctl function in
net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to
obtain potentially sensitive information from kernel stack memory via a
HIDPCONNADD command, because a name field may not end with a '\0'
character. (bnc#1134848)
CVE-2018-17972: An issue was discovered in the proc_pid_stack function
in fs/proc/base.c in the Linux kernel It did not ensure that only root
may inspect the kernel stack of an arbitrary task, allowing a local
attacker to exploit racy stack unwinding and leak kernel task stack
contents. (bnc#1110785)
The following non-security bugs were fixed:
