CVE-2016-3075: Stack-based buffer overflow in the nss_dns implementation of the getnetbyname function in GNU C Library (ak...

Security readout for executives and security teams

This is an old glibc resolver flaw where an overly long network name can crash a vulnerable application. Business impact is primarily denial of service, not confirmed data theft or system takeover. Exposure depends on whether deployed software uses the affected getnetbyname path with attacker-controlled names. Linux systems using glibc before 2.24, or vendor packages lacking the relevant backport, may be exposed. Practical risk is highest where services process untrusted network-name input that reaches NSS DNS getnetbyname. Treat this as moderate operational risk. It affects a foundational Linux library, but the cited impact is application crash and the sources do not show active exploitation. Patch through normal Linux security maintenance, with priority for exposed services and legacy hosts. Mitigation focus: Check vendor glibc advisories for your distribution and release.; Apply the relevant glibc security update or vendor backport.; Prioritize internet-facing services that parse untrusted network names..
