Race condition in the Pipe (IPC) close function in FreeBSD 6.3 and 6.4 allows local users to cause a denial of service (crash) or gain privileges via vectors related to kqueues, which triggers a use after free, leading to a NULL pointer dereference or memory corruption.

Security readout for executives and security teams

This CVE describes a FreeBSD kernel bug where a local user could crash a system or potentially gain higher privileges. The issue is tied to pipe handling and kqueues in FreeBSD 6.3 and 6.4. It is not remotely exploitable based on the supplied evidence. Likely exposure is limited to systems running FreeBSD 6.3 or 6.4 where untrusted or low-privileged local users can execute code. The source bundle does not identify other affected products or versions. Treat this as high priority for legacy FreeBSD systems with local users. Business urgency is lower for externally exposed services alone, but higher where shared hosting, developer shells, or multi-user environments exist. Mitigation focus: Inventory FreeBSD 6.3 and 6.4 systems.; Review FreeBSD-SA-09:13 for vendor-directed remediation.; Apply the vendor-recommended update or patch if applicable..
