Alpine: multiple tor packages: security update to 0.4.4.9-r0

high Tenable Cloud Security Plugin ID 407405

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and
2017.011.30194 (and earlier) are affected by a Use After Free vulnerability. An unauthenticated attacker
could leverage this vulnerability to achieve arbitrary code execution in the context of the current user.
Exploitation of this issue requires user interaction in that a victim must open a malicious file.
(CVE-2021-28550)

- 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 (CPU consumption), aka TROVE-2020-002. (CVE-2020-10592)

- 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. (CVE-2020-10593)

- Tor before 0.4.5.7 allows a remote participant in the Tor directory protocol to exhaust CPU resources on a
target, aka TROVE-2021-001. (CVE-2021-28089)

- Tor before 0.4.5.7 allows a remote attacker to cause Tor directory authorities to exit with an assertion
failure, aka TROVE-2021-002. (CVE-2021-28090)
