Security updates for FreeBSD
The developers of FreeBSD have released security updates to address a number of security vulnerabilities. This includes a bug which could cause a kernel panic when a specially crafted IPV6 packet was received.
The other vulnerabilities addressed are a local code execution vulnerability in FreeBSD 7.0 RELEASE and STABLE, where under certain conditions using
nmount user defined data could be copied to a kernel buffer, and a problem on AMD64 systems, where user and kernel privileges could be manipulated by an attacker when the system was returning from handling an interrupt.
The security advisories listed below include details of the updates or patches users can apply to remedy these issues.
