CVE-2010-4210: Freebsd

High severity, CVSS 7.8. EPSS: 1.1% chance of exploitation in the next 30 days.

The pfs_getextattr function in FreeBSD 7.x before 7.3-RELEASE and 8.x before 8.0-RC1 unlocks a mutex that was not previously locked, which allows local users to cause a denial of service (kernel panic), overwrite arbitrary memory locations, and possibly execute arbitrary code via vectors related to opening a file on a file system that uses pseudofs.

Affected products

• Freebsd Freebsd: from 7.0, before 7.3 (fixed in 7.3); version 8.0 only
