CVE-2015-8778
Published: 19 April 2016
Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access.
From the Ubuntu security team
Szabolcs Nagy discovered that the hcreate functions in the GNU C Library did not properly check its size argument, leading to an integer overflow. An attacker could use to cause a denial of service (application crash) or possibly execute arbitrary code.
