Description
This security bulletin contains information about 19 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2016-7915)
The vulnerability allows a physical attacker to obtain potentially sensitive information or cause DoS condition on the target system.The weakness exists in the hid_input_field function in drivers/hid/hid-core.c due to out-of-bounds read. A physical attacker can gain access to potentially sensitive information or cause the service to crash.
2) Memory leak (CVE-ID: CVE-2017-12190)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to an out-of-memory condition. A local attacker can cause a memory leak and possible system lock up.
3) Privilege escalation (CVE-ID: CVE-2017-13166)
The vulnerability allows a local attacker to gain elevated privileges on the target system.The weakness exists in the V4L2 video driver component of the Google Android kernel due to insufficient validation of user-supplied input. A local attacker can use a specially crafted application and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
4) Null pointer dereference (CVE-ID: CVE-2017-15299)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to the KEYS subsystem mishandles use of add_key for a key that already exists but is uninstantiated. A local attacker can supply specially crafted keys, trigger null pointer dereference and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
5) Error handling (CVE-ID: CVE-2017-16644)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to an error in the hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c in the Linux kernel through in the Linux kernel. A local attacker can supply a specially crafted USB device, trigger improper error handling and cause the system to crash.
Successful exploitation of the vulnerability results in denial of service.
6) Information disclosure (CVE-ID: CVE-2017-16911)
The vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists n the vhci_hcd driver due to insufficient security restrictions. A local attacker with a USB device attached over IP can use the affected driver to bypass security restrictions and access sensitive information, such as kernel memory addresses on the targeted system.
7) Out-of-bounds read (CVE-ID: CVE-2017-16912)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the "get_pipe()" function (drivers/usb/usbip/stub_rx.c) due to out-of-bounds read. A local attacker can supply specially crafted USB over IP packet, trigger memory corruption and cause the service to crash.
8) Memory corruption (CVE-ID: CVE-2017-16913)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the "stub_recv_cmd_submit()" function (drivers/usb/usbip/stub_rx.c) due to boundary error when handling CMD_SUBMIT packets. A local attacker can supply specially crafted USB over IP packet, trigger memory corruption and cause the service to crash.
9) NULL pointer dereference (CVE-ID: CVE-2017-16914)
The vulnerability allows a remote attacker to cause DoS condition on the targtt system.The weakness exists in the "stub_send_ret_submit()" function due to NULL pointer dereference. A remote attacker can cause the service to crash.
10) Use-after-free error (CVE-ID: CVE-2017-18017)
The vulnerability allows a remote attacker to cause DoS condition no the target system.The weakness exists in the tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel due to use-after-free error. A remote attacker can leverage the presence of xt_TCPMSS in an iptables action, trigger memory corruption and cause the system to crash.
11) Memory corruption (CVE-ID: CVE-2017-18204)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the ocfs2_setattr function and is due to boundary error. A local attacker can submit a crafted DIO request, trigger memory corruption and cause the service to crash.
12) Infinite loop (CVE-ID: CVE-2017-18208)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the madvise_willneed function due to infinite loop. A local attacker can trigger use of MADVISE_WILLNEED for a DAX mapping and cause the service to crash.
13) Memory corruption (CVE-ID: CVE-2017-18221)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the __munlock_pagevec function due to boundary error when handling malicious input. A local attacker can execute specially crafted mlockall and munlockall system calls that submit malicious input, corrupt NR_MLOCK accounting and cause the system to crash.
14) NULL pointer dereference (CVE-ID: CVE-2018-1066)
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.The weakness exists in the fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() function due to NULL pointer dereference. A remote attacker can cause the service to crash.
15) Privilege escalation (CVE-ID: CVE-2018-1068)
The vulnerability allows a local attacker to gain elevated privileges on the target system.The weakness exists due to an error in the implementation of 32 bit syscall interface. A local attacker can gain root privileges.
16) Heap out-of-bounds write (CVE-ID: CVE-2018-5332)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the rds_message_alloc_sgs() function due to improper validation of DMA page allocation values. A local attacker can trigger a heap-based out-of-bounds write and cause the system to crash.
17) Null pointer dereference (CVE-ID: CVE-2018-5333)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the rds_cmsg_atomic function due to insufficient handling of user-supplied input. A remote attacker can send a specially crafted HTTP request, trigger NULL pointer dereference and cause the system to crash.
18) Integer overflow (CVE-ID: CVE-2018-6927)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the futex_requeue function due to integer overflow. A local attacker can trigger a negative wake or requeue value and cause the service to crash.
19) Memory corruption (CVE-ID: CVE-2018-7566)
The vulnerability allows a local attacker to write arbitrary files on the target system.The weakness exists due to out-of-bounds write while ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A local attacker can trigger buffer overflow and use after free and reset the pool size manually via ioctl concurrently and write arbitrary files.
