Alpine: multiple tor packages: security update to 0.3.1.8-r1 (deprecated)

high Tenable Cloud Security Plugin ID 400754

Description

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

- In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13,
and 0.3.1 before 0.3.1.9, the replay-cache protection mechanism is ineffective for v2 onion services, aka
TROVE-2017-009. An attacker can send many INTRODUCE2 cells to trigger this issue. (CVE-2017-8819)

- In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13,
and 0.3.1 before 0.3.1.9, remote attackers can cause a denial of service (NULL pointer dereference and
application crash) against directory authorities via a malformed descriptor, aka TROVE-2017-010.
(CVE-2017-8820)

- In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13,
and 0.3.1 before 0.3.1.9, an attacker can cause a denial of service (application hang) via crafted PEM
input that signifies a public key requiring a password, which triggers an attempt by the OpenSSL library
to ask the user for the password, aka TROVE-2017-011. (CVE-2017-8821)

- In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13,
and 0.3.1 before 0.3.1.9, relays (that have incompletely downloaded descriptors) can pick themselves in a
circuit path, leading to a degradation of anonymity, aka TROVE-2017-012. (CVE-2017-8822)

- In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13,
and 0.3.1 before 0.3.1.9, there is a use-after-free in onion service v2 during intro-point expiration
because the expiring list is mismanaged in certain error cases, aka TROVE-2017-013. (CVE-2017-8823)
