Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the GNU C Library.

Software Description: - glibc: GNU C Library - eglibc: GNU C Library

Details:

It was discovered that the GNU C Library incorrectly handled the strxfrm() function. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8982)

It was discovered that an integer overflow existed in the _IO_wstr_overflow() function of the GNU C Library. An attacker could use this to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8983)

It was discovered that the fnmatch() function in the GNU C Library did not properly handle certain malformed patterns. An attacker could use this to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8984)

Alexander Cherepanov discovered a stack-based buffer overflow in the glob implementation of the GNU C Library. An attacker could use this to specially craft a directory layout and cause a denial of service. (CVE-2016-1234)

Florian Weimer discovered a NULL pointer dereference in the DNS resolver of the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2015-5180)

Michael Petlan discovered an unbounded stack allocation in the getaddrinfo() function of the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-3706)

Aldy Hernandez discovered an unbounded stack allocation in the sunrpc implementation in the GNU C Library. An attacker could use this to cause a denial of service. (CVE-2016-4429)

Tim Ruehsen discovered that the getaddrinfo() implementation in the GNU C Library did not properly track memory allocations. An attacker could use this to cause a denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-5417)

Andreas Schwab discovered that the GNU C Library on ARM 32-bit platforms did not properly set up execution contexts. An attacker could use this to cause a denial of service. (CVE-2016-6323)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04 LTS:
libc6 2.23-0ubuntu6

Ubuntu 14.04 LTS:
libc6 2.19-0ubuntu6.10

Ubuntu 12.04 LTS:
libc6 2.15-0ubuntu10.16

After a standard system update you need to reboot your computer to make all the necessary changes.
