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

  - An issue was discovered in GNOME GLib before 2.66.8.
    When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path     that is a dangling symlink, it incorrectly also creates     the target of the symlink as an empty file, which could     conceivably have security relevance if the symlink is     attacker-controlled. (If the path is a symlink to a     file that already exists, then the contents of that     file correctly remain unchanged.)(CVE-2021-28153)

  - An issue was discovered in GNOME GLib before 2.66.7 and     2.67.x before 2.67.4. If g_byte_array_new_take() was     called with a buffer of 4GB or more on a 64-bit     platform, the length would be truncated modulo 2**32,     causing unintended length truncation.(CVE-2021-27218)

  - An issue was discovered in GNOME GLib before 2.66.6 and     2.67.x before 2.67.3. The function g_bytes_new has an     integer overflow on 64-bit platforms due to an implicit     cast from 64 bits to 32 bits. The overflow could     potentially lead to memory corruption.(CVE-2021-27219)

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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:2174 advisory.

    GLib provides the core application building blocks for libraries and applications written in C. It     provides the core object system used in GNOME, the main loop implementation, and a large set of utility     functions for strings and common data structures.

    Security Fix(es):

    * glib: integer overflow in g_bytes_new function on 64-bit platforms due to an implicit cast from 64 bits     to 32 bits (CVE-2021-27219)

According to the versions of the glib2 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - ** DISPUTED ** 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)
