The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-0114 advisory.

  • A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  • read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. (CVE-2022-48564)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
