Synopsis
The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.
Description
The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
- glib2: file_copy_fallback in gio/gfile.c in GNOME GLib does not properly restrict file permissions while a copy operation is in progress (CVE-2019-12450)
- In GNOME GLib 2.56.1, g_markup_parse_context_end_parse() in gmarkup.c has a NULL pointer dereference.
(CVE-2018-16428)
- 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)
- 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)
- A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)
- An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1. When a GDBus- based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based client behaving incorrectly, with an application-dependent impact. (CVE-2024-34397)
Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
Solution
The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
