[USN-3676-2] Linux kernel (Xenial HWE) vulnerabilities

Severity Medium
Affected Packages 9
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

USN-3676-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

Wen Xu discovered that the ext4 filesystem implementation in the Linux
kernel did not properly handle corrupted meta data in some situations. An
attacker could use this to specially craft an ext4 file system that caused
a denial of service (system crash) when mounted. (CVE-2018-1092,
CVE-2018-1093)

It was discovered that the cdrom driver in the Linux kernel contained an
incorrect bounds check. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2018-10940)

It was discovered that the 802.11 software simulator implementation in the
Linux kernel contained a memory leak when handling certain error
conditions. A local attacker could possibly use this to cause a denial of
service (memory exhaustion). (CVE-2018-8087)
