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"
OS | Version | Architecture | Package | Version | Filename |
