| Description: | Summary:
The remote host is missing an update for the Debian 'linux' package(s) announced via the DSA-3945-1 advisory.
Vulnerability Insight:
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
CVE-2014-9940
A use-after-free flaw in the voltage and current regulator driver could allow a local user to cause a denial of service or potentially escalate privileges.
CVE-2017-7346
Li Qiang discovered that the DRM driver for VMware virtual GPUs does not properly check user-controlled values in the vmw_surface_define_ioctl() functions for upper limits. A local user can take advantage of this flaw to cause a denial of service.
CVE-2017-7482
Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not properly verify metadata, leading to information disclosure, denial of service or potentially execution of arbitrary code.
CVE-2017-7533
Fan Wu and Shixiong Zhao discovered a race condition between inotify events and VFS rename operations allowing an unprivileged local attacker to cause a denial of service or escalate privileges.
CVE-2017-7541
A buffer overflow flaw in the Broadcom IEEE802.11n PCIe SoftMAC WLAN driver could allow a local user to cause kernel memory corruption, leading to a denial of service or potentially privilege escalation.
CVE-2017-7542
An integer overflow vulnerability in the ip6_find_1stfragopt() function was found allowing a local attacker with privileges to open raw sockets to cause a denial of service.
CVE-2017-7889
Tommi Rantala and Brad Spengler reported that the mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, allowing a local attacker with access to /dev/mem to obtain sensitive information or potentially execute arbitrary code.
CVE-2017-9605
Murray McAllister discovered that the DRM driver for VMware virtual GPUs does not properly initialize memory, potentially allowing a local attacker to obtain sensitive information from uninitialized kernel memory via a crafted ioctl call.
CVE-2017-10911
/ XSA-216
Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests.
CVE-2017-11176
It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact.
CVE-2017-1000363
Roee Hay reported that the lp driver does not properly bounds-check passed arguments, allowing a local attacker with write access to the kernel command line arguments to execute arbitrary code.
CVE-2017-1000365
It was discovered that argument and environment pointers are not taken properly into account to the imposed size restrictions on arguments and environmental strings passed through RLIMIT_STACK/RLIMIT_INFINITY. A local attacker can take ... [Please see the references for more information on the vulnerabilities]
