sysstat is a package containing a number of performance monitoring utilities for Linux, including sar, mpstat, iostat and sa tools.
A double-free in sysstat’s check_file_actlst() function was discovered.
A local attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All sysstat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sysstat-12.2.1"
