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.

An update of the glib package has been released.

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-2528 advisory.

    - Fix CVEs: CVE-2023-32636, CVE-2023-29499, CVE-2023-32611, CVE-2023-32665, DoS

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2528 advisory.

    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.

    Security Fix(es):

    * glib: GVariant offset table entry size is not checked in is_normal() (CVE-2023-29499)

    * glib: g_variant_byteswap() can take a long time with some non-normal inputs (CVE-2023-32611)

    * glib: Timeout in fuzz_variant_text (CVE-2023-32636)

    * glib: GVariant deserialisation does not match spec for non-normal data (CVE-2023-32665)

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

  - Rejected reason: Rejected by upstream. (CVE-2023-24593, CVE-2023-25180)

  - 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. The GVariant deserialization code is vulnerable to a heap buffer overflow     introduced by the fix for CVE-2023-32665. 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-2023-32665. (CVE-2023-32643)

  - 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 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.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3535-1 advisory.

  - An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also     creates the target of the symlink as an empty file, which could conceivably have security relevance if the     symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents     of that file correctly remain unchanged.) (CVE-2021-28153)

  - The upstream bug report describes this issue as follows: (CVE-2023-29499, CVE-2023-32611, CVE-2023-32665)
