Description

Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.

Affected configurations

• torproject tor (>= 0.3.5 < 0.3.5.10) • torproject tor (> 0.4.1.0 < 0.4.1.9) • torproject tor (> 0.4.2.0 <= 0.4.2.7) • opensuse backports sle 15.0 • opensuse leap 15.1
