mingw-glib2-2.66.7-2.el8

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.

The following packages have been upgraded to a later upstream version:
mingw-glib2 (2.66.7).

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)
* glib: integer overflow in g_byte_array_new_take function when called with a
buffer of 4GB or more on a 64-bit platform (CVE-2021-27218)

listed in the References section.

CVE-2021-27218
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-2021-27219
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.
