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.

Security readout for executives and security teams

CVE-2015-8778 is an old GNU C Library issue fixed before glibc 2.23. A vulnerable application can crash, and in some contexts arbitrary code execution may be possible, if attacker-controlled input reaches the affected __hcreate_r size handling. Exposure is most likely on legacy Linux systems or embedded appliances using glibc/libc6 older than 2.23, especially where applications call hcreate_r with attacker-influenced sizing. The provided affected-product metadata is incomplete. Treat this as a legacy-platform hygiene risk, not a current emergency based on the supplied evidence. Prioritize remediation where old Linux libraries remain in production or embedded products. Mitigation focus: Check OS vendor advisories for fixed glibc/libc6 package versions.; Upgrade glibc/libc6 to a vendor-supported fixed package.; Prioritize unsupported Linux distributions or embedded firmware still using pre-2.23 glibc..
