Detail

Synopsis

A vulnerability in SystemTap could allow a local attacker to create a Denial of Service condition.

Background

SystemTap is a kernel profiling and instrumentation tool.

Description

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

Impact

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

Workaround

Disabling unprivileged mode is a temporary workaround for this vulnerability.

Resolution

All SystemTap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/systemtap-2.0"
