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 •

https://notcve.org/view.php?id=CVE-2023-6377
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 •
CVSS: 7.5EPSS: 81%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-4283
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. Se encontró una vulnerabilidad en X.Org. Este fallo de seguridad se produce porque la función XkbCopyNames dejó un puntero colgante a la memoria liberada, lo que provocó un acceso a la memoria fuera de los límites en solicitudes posteriores de XkbGetKbdByName. • https://access.redhat.com/security/cve/CVE-2022-4283 https://bugzilla.redhat.com/show_bug.cgi?id=2151761 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5NELB7YDWRABYYBG4UPTHRBDTKJRV5M2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DXDF2O5PPLE3SVAJJYUOSAD5QZ4TWQ2G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z67QC4C3I2FI2WRFIUPEHKC36J362MLA https://security.gentoo.org/glsa/202305-30 https://www • CWE-416: Use After Free •
