CVE-2016-3706 [HIGH] GNU C Library regression
Title: GNU C Library regression
Summary: USN-3239-1 introduced a regression in the GNU C Library.
USN-3239-1 fixed vulnerabilities in the GNU C Library. Unfortunately,
the fix for CVE-2016-3706 introduced a regression that in some
circumstances prevented IPv6 addresses from resolving. This update
reverts the change in Ubuntu 12.04 LTS. We apologize for the error.
Original advisory 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)

CVE-2016-6323 glibc: Missing unwind info in __startcontext causes infinite loop in _Unwind_Backtrace
Missing unwind info in __startcontext was found that can lead to infinite loop in _Unwind_Backtrace. Generating stack trace in application code compiled with gccgo can trigger this, causing the affected process hanging up instead of error message.
