RHEL 6 : glib (Unpatched Vulnerability)

medium Nessus Plugin ID 196716

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.

- glib: g_file_replace() with G_FILE_CREATE_REPLACE_DESTINATION creates empty target for dangling symlink (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)

- A flaw was found in GLib. GVariant deserialization fails to validate that the input conforms to the expected format, leading to denial of service. (CVE-2023-29499)

- A flaw was found in GLib. GVariant deserialization is vulnerable to a slowdown issue where a crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32611)

- A flaw was found in glib, where the gvariant deserialization code is vulnerable to a denial of service introduced by additional input validation added to resolve CVE-2023-29499. The offset table validation may be very slow. This bug does not affect any released version of glib but does affect glib distributors who followed the guidance of glib developers to backport the initial fix for CVE-2023-29499. (CVE-2023-32636)

- A flaw was found in GLib. GVariant deserialization is vulnerable to an exponential blowup issue where a crafted GVariant can cause excessive processing, leading to denial of service. (CVE-2023-32665)

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.
