CVE-2015-8985: The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers to...

Security readout for executives and security teams

This issue can make software using GNU C Library regular-expression handling crash when processing certain extended regular expressions. It is a denial-of-service risk, not described in the sources as data theft or code execution. Business urgency depends on whether exposed services process attacker-controlled regex patterns or regex-search input. Likely exposure is Linux systems or applications using vulnerable glibc/libc6 regex processing, especially services accepting untrusted regular expressions or regex-search text. Exact affected versions are not enumerated in the bundle, so exposure must be confirmed against distribution package advisories. Treat as a targeted availability risk in systems that expose regex processing to users. It is not supported by the provided evidence as actively exploited or code-execution capable, but patching core libraries should follow normal maintenance controls. Mitigation focus: Check Linux distribution guidance for affected glibc/libc6 packages.; Apply vendor-supported glibc/libc6 security updates where available.; Prioritize internet-facing services that process user-controlled regex input..
