EulerOS Virtualization 3.0.2.2 : glib2 (EulerOS-SA-2020-1456)

critical Nessus Plugin ID 135618

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL).
Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions are used for files, default file permissions are used. This is similar to CVE-2019-12450.(CVE-2019-13012)

- file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress.
Instead, default permissions are used.(CVE-2019-12450)

- GNOME GLib 2.56.1 has an out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c, related to utf8_str().(CVE-2018-16429)

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.

Solution

Update the affected glib2 packages.
