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.

CVE-2015-8778 [CRITICAL] CWE-190 glibc: Integer overflow in hcreate and hcreate_r
glibc: Integer overflow in hcreate and hcreate_r
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.
An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution.
Mitigation: Do not use any applications which call hcreate or hcreate_r with a large size argument.
These functions are used only rarely, and most callers supply a constant argument. Other applications calculate the size argument in such a w
