script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :
- The hid_input_field function in drivers/hid/hid-core.c
in the Linux kernel before 4.6 allows physically
proximate attackers to obtain sensitive information
from kernel memory or cause a denial of service
(out-of-bounds read) by connecting a device, as
demonstrated by a Logitech DJ receiver.(CVE-2016-7915)
- In the Linux kernel through 4.14.13,
drivers/block/loop.c mishandles lo_release
serialization, which allows attackers to cause a denial
of service (__lock_acquire use-after-free) or possibly
have unspecified other impact.(CVE-2018-5344)
- In the Linux kernel through 4.14.13, the
rds_cmsg_atomic() function in 'net/rds/rdma.c'
mishandles cases where page pinning fails or an invalid
address is supplied by a user. This can lead to a NULL
pointer dereference in rds_atomic_free_op() and thus to
a system panic.(CVE-2018-5333)
- In the Linux kernel through 4.14.13, the
rds_message_alloc_sgs() function does not validate a
value that is used during DMA page allocation, leading
to a heap-based out-of-bounds write (related to the
rds_rdma_extra_size() function in 'net/rds/rdma.c') and
thus to a system panic. Due to the nature of the flaw,
privilege escalation cannot be fully ruled out,
although we believe it is unlikely.(CVE-2018-5332)
- A flaw was found in the upstream kernel Skcipher
component. This vulnerability affects the
skcipher_recvmsg function of the component Skcipher.
The manipulation with an unknown input leads to a
privilege escalation vulnerability.(CVE-2017-13215)
- The tcpmss_mangle_packet function in
net/netfilter/xt_TCPMSS.c in the Linux kernel before
4.11, and 4.9.x before 4.9.36, allows remote attackers
to cause a denial of service (use-after-free and memory
corruption) or possibly have unspecified other impact
by leveraging the presence of xt_TCPMSS in an iptables
action.(CVE-2017-18017)
- The Salsa20 encryption algorithm in the Linux kernel
before 4.14.8 does not correctly handle zero-length
inputs, allowing a local attacker able to use the
AF_ALG-based skcipher interface
(CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of
service (uninitialized-memory free and kernel crash) or
have unspecified other impact by executing a crafted
sequence of system calls that use the blkcipher_walk
API. Both the generic implementation
(crypto/salsa20_generic.c) and x86 implementation
(arch/x86/crypto/salsa20_glue.c) of Salsa20 were
vulnerable.(CVE-2017-17805)
- The HMAC implementation (crypto/hmac.c) in the Linux
kernel before 4.14.8 does not validate that the
underlying cryptographic hash algorithm is unkeyed,
allowing a local attacker able to use the AF_ALG-based
hash interface (CONFIG_CRYPTO_USER_API_HASH) and the
SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a
kernel stack buffer overflow by executing a crafted
sequence of system calls that encounter a missing SHA-3
initialization.(CVE-2017-17806)
- he KEYS subsystem in the Linux kernel before 4.14.6
omitted an access-control check when adding a key to
the current task's 'default request-key keyring' via
the request_key() system call, allowing a local user to
use a sequence of crafted system calls to add keys to a
keyring with only Search permission (not Write
permission) to that keyring, related to
construct_get_dest_keyring() in
security/keys/request_key.c.(CVE-2017-17807)
- The Linux Kernel 2.6.32 and later are affected by a
denial of service, by flooding the diagnostic port 0x80
an exception can be triggered leading to a kernel
panic.(CVE-2017-1000407)
- The XFRM dump policy implementation in
net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11
allows local users to gain privileges or cause a denial
of service (use-after-free) via a crafted SO_RCVBUF
setsockopt system call in conjunction with
XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939)
- The dccp_disconnect function in net/dccp/proto.c in the
Linux kernel through 4.14.3 allows local users to gain
privileges or cause a denial of service
(use-after-free) via an AF_UNSPEC connect system call
during the DCCP_LISTEN state.(CVE-2017-8824)
- net/netfilter/nfnetlink_cthelper.c in the Linux kernel
through 4.14.4 does not require the CAP_NET_ADMIN
capability for new, get, and del operations, which
allows local users to bypass intended access
restrictions because the nfnl_cthelper_list data
structure is shared across all net
namespaces.(CVE-2017-17448)
- Use-after-free vulnerability in the snd_pcm_info
function in the ALSA subsystem in the Linux kernel
allows attackers to gain privileges via unspecified
vectors.(CVE-2017-0861)
- The usb_destroy_configuration function in
drivers/usb/core/config.c in the USB core subsystem in
the Linux kernel through 4.14.5 does not consider the
maximum number of configurations and interfaces before
attempting to release resources, which allows local
users to cause a denial of service (out-of-bounds write
access) or possibly have unspecified other impact via a
crafted USB device.(CVE-2017-17558)
- The __netlink_deliver_tap_skb function in
net/netlink/af_netlink.c in the Linux kernel through
4.14.4, when CONFIG_NLMON is enabled, does not restrict
observations of Netlink messages to a single net
namespace, which allows local users to obtain sensitive
information by leveraging the CAP_NET_ADMIN capability
to sniff an nlmon interface for all Netlink activity on
the system.(CVE-2017-17449)
- net/netfilter/xt_osf.c in the Linux kernel through
4.14.4 does not require the CAP_NET_ADMIN capability
for add_callback and remove_callback operations, which
allows local users to bypass intended access
restrictions because the xt_osf_fingers data structure
is shared across all net namespaces.(CVE-2017-17450)
- The bnep_add_connection function in
net/bluetooth/bnep/core.c in the Linux kernel before
3.19 does not ensure that an l2cap socket is available,
which allows local users to gain privileges via a
crafted application.(CVE-2017-15868)
- The einj_error_inject function in
drivers/acpi/apei/einj.c in the Linux kernel allows
local users to simulate hardware errors and
consequently cause a denial of service by leveraging
failure to disable APEI error injection through EINJ
when securelevel is set.(CVE-2016-3695)
