A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34. Se presenta un fallo en el archivo bfd/pef.c de binutils. Un atacante que pueda enviar un archivo PEF diseñado para que sea analizado por objdump podría causar un desbordamiento del búfer de pila -) lectura fuera de límites que podría tener un impacto en la disponibilidad de la aplicación. • https://bugzilla.redhat.com/show_bug.cgi?id=1911437 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4KOK3QWSVOUJWJ54HVGIFWNLWQ5ZY4S6 https://security.gentoo.org/glsa/202107-24 https://security.netapp.com/advisory/ntap-20210212-0007 • CWE-20: Improper Input Validation •

get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743. La función get_gate_page en el archivo mm/gup.c en el kernel de Linux versiones 5.7.x y versiones 5.8.x anteriores a 5.8.7, permite una escalada de privilegios debido al conteo de referencias incorrecto (causado por el manejo inapropiado de una página de puerta) de la página de estructura que respalda la página vsyscall. El resultado es un subdesbordamiento del conteo. • http://www.openwall.com/lists/oss-security/2020/09/10/4 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.8.7 https://git.kernel.org/linus/8891adc61dce2a8a41fc0c23262b681c3ec4b73a https://git.kernel.org/linus/9fa2dd946743ae6f30dc4830da19147bf100a7f2 https://security.netapp.com/advisory/ntap-20201001-0003 https://www.openwall.com/lists/oss-security/2020/09/08/4 • CWE-672: Operation on a Resource after Expiration or Release •

https://notcve.org/view.php?id=CVE-2020-13631
SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c. SQLite versiones anteriores a la versión 3.32.0, permite que una tabla virtual sea renombrada con el nombre de una de sus tablas shadow, relacionada con los archivos alter.c y build.c. A flaw was found in the virtual table implementation of SQLite. This flaw allows an attacker who can execute SQL statements to rename a virtual table to the name of one of its shadow tables, leading to potential data corruption. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 https://bugs.chromium.org/p/chromium/issues/detail?id=1080459 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://lists.apache.org/thread.html/rc713534b10f9daeee2e0990239fa407e2118e4aa9e88a7041177497c%40%3Cissues.guacamole.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists&# • CWE-20: Improper Input Validation •
