The SafeSocks option in Tor before 0.4.7.13 has a logic error in which the unsafe SOCKS4 protocol can be used but not the safe SOCKS4a protocol, aka TROVE-2022-002.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The SafeSocks option in Tor before 0.4.7.13 has a logic error in which the unsafe SOCKS4 protocol can be     used but not the safe SOCKS4a protocol, aka TROVE-2022-002. (CVE-2023-23589)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202305-11 (Tor: Multiple Vulnerabilities)

  - Tor before 0.3.5.16, 0.4.5.10, and 0.4.6.7 mishandles the relationship between batch-signature     verification and single-signature verification, leading to a remote assertion failure, aka TROVE-2021-007.
    (CVE-2021-38385)

  - Tor 0.4.7.x before 0.4.7.8 allows a denial of service via the wedging of RTT estimation. (CVE-2022-33903)
