USN-3381-1: Linux kernel vulnerabilities
Publication date
7 August 2017
Overview
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux - Linux kernel
Details
Peter Pi discovered that the colormap handling for frame buffer devices in
the Linux kernel contained an integer overflow. A local attacker could use
this to disclose sensitive information (kernel memory). (CVE-2016-8405)
It was discovered that the Linux kernel did not properly restrict
RLIMIT_STACK size. A local attacker could use this in conjunction with
another vulnerability to possibly execute arbitrary code.
(CVE-2017-1000365)
It was discovered that SELinux in the Linux kernel did not properly handle
empty writes to /proc/pid/attr. A local attacker could use this to cause a
denial of service (system crash). (CVE-2017-2618)
石磊 discovered that the RxRPC Kerberos 5 ticket handling code in the
Linux kernel did not properly verify metadata. A remote attacker could use
this to cause a denial of service...

Update instructions
After a standard system update you need to reboot your computer to make all the necessary changes.
Learn more about how to get the fixes.The problem can be corrected by updating your system to the following package versions:
Reduce your security exposure
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
