CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2023-39198 – Kernel: qxl: race condition leading to use-after-free in qxl_mode_dumb_create()
https://notcve.org/view.php?id=CVE-2023-39198
A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation. Se encontró una condición de ejecución en el controlador QXL del kernel de Linux. La función qxl_mode_dumb_create() desreferencia el qobj devuelto por qxl_gem_object_create_with_handle(), pero el identificador es el único que contiene una referencia a él. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39198 https://bugzilla.redhat.com/show_bug.cgi?id=2218332 https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html • CWE-416: Use After Free •
CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2023-5824 – Squid: dos against http and https
https://notcve.org/view.php?id=CVE-2023-5824
Squid is vulnerable to Denial of Service attack against HTTP and HTTPS clients due to an Improper Handling of Structural Elements bug. Squid es vulnerable a ataques de Denegación de Servicio contra clientes HTTP y HTTPS debido a un error en el manejo inadecuado de elementos estructurales. A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service. • https://access.redhat.com/errata/RHSA-2023:7465 https://access.redhat.com/errata/RHSA-2023:7668 https://access.redhat.com/errata/RHSA-2024:0072 https://access.redhat.com/errata/RHSA-2024:0397 https://access.redhat.com/errata/RHSA-2024:0771 https://access.redhat.com/errata/RHSA-2024:0772 https://access.redhat.com/errata/RHSA-2024:0773 https://access.redhat.com/errata/RHSA-2024:1153 https://access.redhat.com/security/cve/CVE-2023-5824 https://bugzilla.redhat.com/show • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.5EPSS: 83%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-2023-39194
A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an information disclosure. Se encontró una falla en el subsistema XFRM del kernel de Linux. La falla específica existe en el procesamiento de filtros de estado, lo que puede resultar en una lectura más allá del final de un búfer asignado. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39194 https://bugzilla.redhat.com/show_bug.cgi?id=2226788 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://www.zerodayinitiative.com/advisories/ZDI-CAN-18111 • CWE-125: Out-of-bounds Read •
