"According to the versions of the php packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :
- In PHP versions 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8 various XML functions
rely on libxml global state to track configuration variables, like whether external entities are loaded.
This state is assumed to be unchanged unless the user explicitly changes it by calling appropriate
function. However, since the state is process-global, other modules - such as ImageMagick - may also use
this library within the same process, and change that global state for their internal purposes, and leave
it in a state where external entities loading is enabled. This can lead to the situation where external
XML is parsed with external entities loaded, which can lead to disclosure of any local files accessible to
PHP. This vulnerable state may persist in the same process across many requests, until the process is shut
down. (CVE-2023-3823)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
