CVE-2014-9761

Priority
Description
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or
libc6) before 2.23 allow context-dependent attackers to cause a denial of
service (application crash) or possibly execute arbitrary code via a long
argument to the (1) nan, (2) nanf, or (3) nanl function.
Ubuntu-Description
Joseph Myers discovered that the GNU C Library did not properly
handle long arguments to functions returning a representation of
Not a Number (NaN). An attacker could use this to cause a denial
of service (stack exhaustion leading to an application crash) or
possibly execute arbitrary code.
Notes
tyhicksUSN-2985-1 initially fixed this issue but it caused a regression and
the change was backed out by USN-2985-2. This issue will be fixed in a future
update.
