According to the version of the glib2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor’s position is ‘Realistically this is not a security issue. The standard pattern is for callers to provide a static list of option entries in a fixed number of calls to g_option_group_add_entries().’ The researcher states that this pattern is undocumented.(CVE-2020-35457)

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.
