A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. Se observó un problema de carrera en el la función vt_k_ioctl en el archivo drivers/tty/vt/vt_ioctl.c en el kernel de Linux, que puede causar una lectura fuera de límites en vt ya que el acceso de escritura a vc_mode no está protegido por el bloqueo de vt_ioctl (KDSETMDE). La mayor amenaza de esta vulnerabilidad es para la confidencialidad de los datos • https://bugzilla.redhat.com/show_bug.cgi?id=1999589 https://github.com/torvalds/linux/commit/2287a51ba822384834dafc1c798453375d1107c7 https://security.netapp.com/advisory/ntap-20221028-0003 https://www.openwall.com/lists/oss-security/2021/09/01/4 https://access.redhat.com/security/cve/CVE-2021-3753 • CWE-125: Out-of-bounds Read CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib. Un atacante que controle un servidor HTTP malicioso al que se conecte un cliente HTTP (como un navegador web), podría desencadenar una Denegación de Servicio por Expresión Regular (ReDOS) durante una petición de autenticación con una carga útil especialmente diseñada que sea enviada por el servidor al cliente. • https://bugs.python.org/issue43075 https://bugzilla.redhat.com/show_bug.cgi?id=1995234 https://github.com/python/cpython/commit/7215d1ae25525c92b026166f9d5cac85fb https://github.com/python/cpython/pull/24391 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://security.netapp.com/advisory/ntap-20220407-0001 https://ubuntu.com/security/CVE-2021-3733 https://access.redhat.com/security/cve/CVE-2021-3733 • CWE-400: Uncontrolled Resource Consumption •

curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. curl versiones 7.61.0 hasta 7.76.1, sufre de exposición de un elemento de datos a una sesión equivocada debido a un error en el código para la función CURLOPT_SSL_CIPHER_LIST cuando libcurl es construído para usar la biblioteca TLS de Schannel. El ajuste de cifrado seleccionado se almacenaba en una única variable "static" en la biblioteca, lo que tiene el sorprendente efecto secundario de que si una aplicación establece múltiples transferencias concurrentes, la última que ajusta los cifrados controlará accidentalmente el ajuste usado por todas las transferencias. En el peor de los casos, esto debilita significativamente la seguridad del transporte • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2021-22897.html https://github.com/curl/curl/commit/bbb71507b7bab52002f9b1e0880bed6a32834511 https://hackerone.com/reports/1172857 https://security.netapp.com/advisory/ntap-20210727-0007 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html • CWE-668: Exposure of Resource to Wrong Sphere CWE-840: Business Logic Errors •
