https://notcve.org/view.php?id=CVE-2024-0408
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL. Se encontró una falla en el servidor X.Org. El código GLX PBuffer no llama al gancho XACE al crear el búfer, dejándolo sin etiquetar. • https://access.redhat.com/errata/RHSA-2024:0320 https://access.redhat.com/errata/RHSA-2024:2169 https://access.redhat.com/errata/RHSA-2024:2170 https://access.redhat.com/errata/RHSA-2024:2995 https://access.redhat.com/errata/RHSA-2024:2996 https://access.redhat.com/security/cve/CVE-2024-0408 https://bugzilla.redhat.com/show_bug.cgi?id=2257689 https://lists.debian.org/debian-lts-announce/2024/01/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce@lists& • CWE-158: Improper Neutralization of Null Byte or NUL Character •

https://notcve.org/view.php?id=CVE-2024-0409
A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. Se encontró una falla en el servidor X.Org. El código del cursor tanto en Xephyr como en Xwayland utiliza el tipo incorrecto de privado en el momento de la creación. • https://access.redhat.com/errata/RHSA-2024:0320 https://access.redhat.com/errata/RHSA-2024:2169 https://access.redhat.com/errata/RHSA-2024:2170 https://access.redhat.com/errata/RHSA-2024:2995 https://access.redhat.com/errata/RHSA-2024:2996 https://access.redhat.com/security/cve/CVE-2024-0409 https://bugzilla.redhat.com/show_bug.cgi?id=2257690 https://lists.debian.org/debian-lts-announce/2024/01/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce@lists& • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-6478
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information. Se encontró una falla en xorg-server. Una solicitud especialmente manipulada a RRChangeProviderProperty o RRChangeOutputProperty puede desencadenar un desbordamiento de enteros que puede provocar la divulgación de información confidencial. This vulnerability allows local attackers to disclose sensitive information on affected installations of X.Org Server. • http://www.openwall.com/lists/oss-security/2023/12/13/1 https://access.redhat.com/errata/RHSA-2023:7886 https://access.redhat.com/errata/RHSA-2024:0006 https://access.redhat.com/errata/RHSA-2024:0009 https://access.redhat.com/errata/RHSA-2024:0010 https://access.redhat.com/errata/RHSA-2024:0014 https://access.redhat.com/errata/RHSA-2024:0015 https://access.redhat.com/errata/RHSA-2024:0016 https://access.redhat.com/errata/RHSA-2024:0017 https://access.redhat.com& • CWE-190: Integer Overflow or Wraparound •

A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. Se encontró una falla en xorg-server. Consultar o cambiar las acciones de los botones XKB, como pasar de un panel táctil a un mouse, puede provocar lecturas y escrituras de memoria fuera de los límites. • http://www.openwall.com/lists/oss-security/2023/12/13/1 https://access.redhat.com/errata/RHSA-2023:7886 https://access.redhat.com/errata/RHSA-2024:0006 https://access.redhat.com/errata/RHSA-2024:0009 https://access.redhat.com/errata/RHSA-2024:0010 https://access.redhat.com/errata/RHSA-2024:0014 https://access.redhat.com/errata/RHSA-2024:0015 https://access.redhat.com/errata/RHSA-2024:0016 https://access.redhat.com/errata/RHSA-2024:0017 https://access.redhat.com& • CWE-125: Out-of-bounds Read •

In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception.
