An update that solves 12 vulnerabilities and has 8 fixes is
now available.
Description:
The SUSE Linux Enterprise 12 SP2 kernel version 4.4.121 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 was possible to send a crafted sequence of SACKs
which would fragment the TCP retransmission queue. A remote attacker may
have been 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 would 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-2019-12382: An issue was discovered in drm_load_edid_firmware in
drivers/gpu/drm/drm_edid_load.c in the Linux kernel There is an
unchecked kstrdup of fwstr, which may have allowed an attacker to cause
a denial of service (NULL pointer dereference and system crash).
(bnc#1136586)
- 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 have been 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 have
allowed local users to obtain sensitive information by reading
uninitialized data in the filesystem. (bnc#1135281)
- CVE-2018-7191: In the tun subsystem in the Linux kernel,
dev_get_valid_name was not called before register_netdevice. This
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. This is similar to CVE-2013-4343. (bnc#1135603)
- 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 had a race condition when reading
/proc/pid/stat. (bnc#1131543)
- CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in
net/rds/tcp.c in the Linux kernel There was a race condition leading to
a use-after-free, related to net namespace cleanup. (bnc#1134537)
- 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 have ended 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:
- cifs: keep FileInfo handle live during oplock break (bsc#1106284,
bsc#1131565).
- ftrace/x86_64: Emulate call function while updating in breakpoint
handler (bsc#1099658).
- kabi: drop LINUX_MIB_TCPWQUEUETOOBIG snmp counter (bsc#1137586).
- kabi: move sysctl_tcp_min_snd_mss to preserve struct net layout
(bsc#1137586).
- mwifiex: Fix heap overflow in mwifiex_uap_parse_tail_ies() (bsc#1136935).
- tcp: add tcp_min_snd_mss sysctl (bsc#1137586).
- tcp: enforce tcp_min_snd_mss in tcp_mtu_probing() (bsc#1137586).
- tcp: limit payload size of sacked skbs (bsc#1137586).
- tcp: tcp_fragment() should apply sane memory limits (bsc#1137586).
- x86_64: Add gap to int3 to allow for call emulation (bsc#1099658).
- x86_64: Allow breakpoints to emulate call instructions (bsc#1099658).
- xen-swiotlb: fix the check condition for xen_swiotlb_free_coherent
(bnc#1134596).
- xen-swiotlb: use actually allocated size on check physical continuous
(bnc#1134596).
