Stack-based buffer overflow in the catopen function 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 a long catalog name.

Security readout for executives and security teams

CVE-2015-8779 is a memory corruption flaw in GNU C Library before 2.23. A long message catalog name passed to catopen could crash an affected application and may allow code execution in some contexts. Business urgency depends on whether old or unpatched Linux systems remain in use. Most exposure is legacy Linux hosts, containers, appliances, or embedded systems using unpatched glibc/libc6 before 2.23 or vendor packages lacking the backport. Internet exposure is indirect and depends on applications that expose catalog-name input. Treat this as a legacy platform hygiene issue with possible high impact in narrow conditions. It should be remediated through standard OS patching, especially on unsupported Linux systems and long-lived appliances. Mitigation focus: Apply the relevant Linux distribution glibc/libc6 security update.; Upgrade to glibc 2.23 or a vendor-backported fixed package.; Check vendor advisories for exact fixed package versions..
