A security issue affects these releases of Ubuntu and its
derivatives:
Several security issues were fixed in the kernel.
An integer overflow was discovered in the stack randomization feature of
the Linux kernel on 64 bit platforms. A local attacker could exploit this
flaw to bypass the Address Space Layout Randomization (ASLR) protection
mechanism. (CVE-2015-1593)
An information leak was discovered in the Linux Kernel’s handling of
userspace configuration of the link layer control (LLC). A local user could
exploit this flaw to read data from other sysctl settings. (CVE-2015-2041)
An information leak was discovered in how the Linux kernel handles setting
the Reliable Datagram Sockets (RDS) settings. A local user could exploit
this flaw to read data from other sysctl settings. (CVE-2015-2042)
The problem can be corrected by updating your system to the following
package version:
To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.

A security issue affects these releases of Ubuntu and its
derivatives:
Several security issues were fixed in the kernel.
It was discovered that the Linux kernel’s Infiniband subsystem did not
properly sanitize its input parameters while registering memory regions
from userspace. A local user could exploit this flaw to cause a denial of
service (system crash) or to potentially gain administrative privileges.

A security issue affects these releases of Ubuntu and its
derivatives:
Several security issues were fixed in the kernel.
Sun Baoliang discovered a use after free flaw in the Linux kernel’s SCTP
(Stream Control Transmission Protocol) subsystem during INIT collisions. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) or potentially escalate their privileges on the system.
(CVE-2015-1421)
Marcelo Leitner discovered a flaw in the Linux kernel’s routing of packets
to too many different dsts/too fast. A remote attacker on the same subnet can exploit this
flaw to cause a denial of service (system crash). (CVE-2015-1465)

Recently we told you about malware inside of Google Play and we also alerted you to the resurrection of Simplocker, a dangerous ransomware that has started its second infection wave. Hopefully, you are convinced that you need to seek a top security application for your Android device. It’s just not safe out there any longer.
However, how can you be sure that our security application is doing its job correctly and extensively?
Some people doubt marketing talk on vendor websites, but we know you cannot start testing every apk file or entering the dark side site of Internet just to see if our solution works. That’s why Avast has chosen to submit our products to third party, independent testing labs.
AV-TEST is a well-known testing laboratory for mobile security. Recently, they tested 31 mobile security products for Android focusing “on malware detection and usability, including performance and false positives”.
They used 2,950 different malware samples and Avast Mobile Security blocked 100% of them. The malware set was a very recent one: malware in the wild in the last 4 weeks.
More?
Avast Mobile Security did not commit any mistake when tested with 1,932 legitimate apps from the Google Play Store and 981 legitimate apps from third party app stores. The better of the two worlds: protection and usability.
In addition, all this protection, according to AV-TEST, did not “impact the battery life”, or “slow down the device during normal usage”, and “does not generate too much traffic”.
Avast Mobile Security earned the AV-TEST certification.
The testing Lab gives a thumbs up for all the other security features that you can find in Avast Mobile Security:
