Percentile

77.5%

According to the versions of the python-setuptools packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • Python Packaging Authority (PyPA) setuptools before 65.5.1 allows remote attackers to cause a denial of service via HTML in a crafted package or custom PackageIndex page. There is a Regular Expression Denial of Service (ReDoS) in package_index.py. (CVE-2022-40897)

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.
