An update that solves 9 vulnerabilities and has 9 fixes is
now available.
Description:
The SUSE Linux Enterprise 11 SP4 kernel version 3.0.101 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 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 will fragment the TCP retransmission queue. An 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 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-2014-9710: The Btrfs implementation in the Linux kernel did not
ensure that the visible xattr state is consistent with a requested
replacement, which allowed local users to bypass intended ACL settings
and gain privileges via standard filesystem operations (1) during an
xattr-replacement time window, related to a race condition, or (2) after
an xattr-replacement attempt that fails because the data did not fit
(bnc#923908).
- 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-2019-11190: 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-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).
- 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-2019-11486: The Siemens R3964 line discipline driver in
drivers/tty/n_r3964.c in the Linux kernel had multiple race conditions
(bnc#1133188).
The following non-security bugs were fixed:
- cifs: fix uninitialized memory access (bsc#1120326).
- kabi: drop LINUX_MIB_TCPWQUEUETOOBIG snmp counter (bsc#1137586).
- kernel: Add CEX7 toleration support (bsc#1131295).
- net: ipsec: fix a kernel oops caused by reentrant workqueue
(bsc#1119314).
- 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/MCE: Handle "nosmt" offlining properly (bsc#1134729).
- xfs: do not cache inodes read through bulkstat (bsc#1134102).
