Amazon Linux 2 : glib2 (ALAS-2021-1711)

high Nessus Plugin ID 153898


The remote Amazon Linux 2 host is missing a security update.


The version of glib2 installed on the remote host is prior to 2.56.1-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1711 advisory.

- 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Run 'yum update glib2' to update your system.
