According to the versions of the python2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

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

  • An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. (CVE-2022-48565)

  • An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
