CVSS: 5.5EPSS: 0%CPEs: 15EXPL: 0CVE-2024-0408 – Xorg-x11-server: selinux unlabeled glx pbuffer
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-2020-26117
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. En los archivos rfb/CSecurityTLS.cxx y rfb/CSecurityTLS.java en TigerVNC versiones anteriores a 1.11.0, los espectadores manejan inapropiadamente las excepciones del certificado TLS. Almacenan los certificados como autoridades, lo que significa que el propietario de un certificado puede hacerse pasar por cualquier servidor después de que un cliente haya agregado una excepción • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00024.html https://bugzilla.opensuse.org/show_bug.cgi?id=1176733 https://github.com/TigerVNC/tigervnc/commit/20dea801e747318525a5859fe4f37c52b05310cb https://github.com/TigerVNC/tigervnc/commit/7399eab79a4365434d26494fa1628ce1eb91562b https://github.com/TigerVNC/tigervnc/commit/b30f10c681ec87720cff85d490f67098568a9cba https://github.com/TigerVNC/tigervnc/commit/f029745f63ac7d22fb91639b2cb5b3ab56134d6e https://githu • CWE-295: Improper Certificate Validation CWE-296: Improper Following of a Certificate's Chain of Trust •
CVSS: 7.2EPSS: 0%CPEs: 2EXPL: 1CVE-2019-15695 – tigervnc: Stack buffer overflow in CMsgReader::readSetCursor
https://notcve.org/view.php?id=CVE-2019-15695
TigerVNC version prior to 1.10.1 is vulnerable to stack buffer overflow, which could be triggered from CMsgReader::readSetCursor. This vulnerability occurs due to insufficient sanitization of PixelFormat. Since remote attacker can choose offset from start of the buffer to start writing his values, exploitation of this vulnerability could potentially result into remote code execution. This attack appear to be exploitable via network connectivity. TigerVNC versión anterior a 1.10.1, es vulnerable al desbordamiento de búfer de pila, que podría ser activada desde la función CMsgReader::readSetCursor. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00039.html https://github.com/CendioOssman/tigervnc/commit/05e28490873a861379c943bf616614b78b558b89 https://github.com/TigerVNC/tigervnc/releases/tag/v1.10.1 https://www.openwall.com/lists/oss-security/2019/12/20/2 https://access.redhat.com/security/cve/CVE-2019-15695 https://bugzilla.redhat.com/show_bug.cgi?id=1790318 • CWE-121: Stack-based Buffer Overflow CWE-754: Improper Check for Unusual or Exceptional Conditions CWE-787: Out-of-bounds Write •
