SystemTap: Denial of service

SystemTap: Denial of service A vulnerability in SystemTap could allow a local attacker to create a Denial of Service condition. systemtap 2014-06-05 2014-06-05 405345 local 2.0 2.0

SystemTap is a kernel profiling and instrumentation tool.

SystemTap does not properly handle DWARF expressions when unwinding the stack.

A local attacker with SystemTap permissions could trigger a kernel panic, causing a Denial of Service condition.

Disabling unprivileged mode is a temporary workaround for this vulnerability.

All SystemTap users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-util/systemtap-2.0"
