CVSS: 5.0EPSS: 0%CPEs: 14EXPL: 1CVE-2020-1733 – ansible: insecure temporary directory when running become_user from become directive
https://notcve.org/view.php?id=CVE-2020-1733
A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p <dir>"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/<pid>/cmdline'. Se encontró un fallo de condición de carrera en Ansible Engine versiones 2.7.17 y anteriores, 2.8.9 y anteriores, 2.9.6 y anteriores, cuando se ejecuta un playbook con un usuario convertido a no privilegiado. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1733 https://github.com/ansible/ansible/issues/67791 https://lists.debian.org/debian-lts-announce/2020/05/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DKPA4KC3OJSUFASUYMG66HKJE7ADNGFW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MRRYUU5ZBLPBXCYG6CFP35D64NP2UB2S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WQVOQD4VAIXXTVQAJK • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-377: Insecure Temporary File •
CVSS: 7.5EPSS: 0%CPEs: 55EXPL: 1CVE-2019-19906 – cyrus-sasl: denial of service in _sasl_add_string function
https://notcve.org/view.php?id=CVE-2019-19906
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. cyrus-sasl (también se conoce como Cyrus SASL) versión 2.1.27, presenta una escritura fuera de límites conllevando a una denegación de servicio remota no autenticada en OpenLDAP por medio de un paquete LDAP malformado. El bloqueo de OpenLDAP es causado en última instancia por un error por un paso en la función _sasl_add_string en el archivo common.c en cyrus-sasl. • http://seclists.org/fulldisclosure/2020/Jul/23 http://seclists.org/fulldisclosure/2020/Jul/24 http://www.openwall.com/lists/oss-security/2022/02/23/4 https://github.com/cyrusimap/cyrus-sasl/issues/587 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2019/12/msg00027.h • CWE-193: Off-by-one Error CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

Hardlink before 0.1.2 operates on full file system objects path names which can allow a local attacker to use this flaw to conduct symlink attacks. Hardlink versiones anteriores a 0.1.2, opera en nombres de ruta de objetos del sistema de archivos completo, lo que puede permitir a un atacante local usar este fallo para realizar ataques de tipo symlink. • https://access.redhat.com/security/cve/cve-2011-3632 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645516 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-3632 https://security-tracker.debian.org/tracker/CVE-2011-3632 https://www.openwall.com/lists/oss-security/2011/10/15/2 https://www.openwall.com/lists/oss-security/2011/10/20/6 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, leading to hardlink executable crash or potentially arbitrary code execution with user privileges. Hardlink versiones anteriores a 0.1.2, presenta múltiples desbordamientos de enteros que conllevan a desbordamientos de búfer en la región heap de la memoria debido a la manera en que se realiza la concatenación de las longitudes de cadena en el cálculo del espacio de memoria requerido para ser usado. Un atacante remoto podría proveer un árbol de directorios especialmente diseñado y engañar al usuario local para consolidarlo, conllevando a un bloqueo del ejecutable de hardlink o una ejecución de código potencialmente arbitraria con privilegios de usuario. • https://access.redhat.com/security/cve/cve-2011-3631 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645516 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-3631 https://security-tracker.debian.org/tracker/CVE-2011-3631 • CWE-190: Integer Overflow or Wraparound •

Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. A remote attacker could provide a specially-crafted directory tree, and trick the local user into consolidating it, leading to hardlink executable crash, or, potentially arbitrary code execution with the privileges of the user running the hardlink executable. Hardlink versiones anteriores a 0.1.2, sufre de múltiples fallos de desbordamiento de búfer en la región stack de la memoria debido a la manera en que son procesados los árboles de directorios con directorios profundamente anidados. Un atacante remoto podría proveer un árbol de directorios especialmente diseñado y engañar al usuario local para consolidarlo, conllevando a un bloqueo del ejecutable de hardlink o una ejecución de código potencialmente arbitraria con los privilegios del usuario que ejecuta el ejecutable de hardlink. • https://access.redhat.com/security/cve/cve-2011-3630 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645516 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2011-3630 https://security-tracker.debian.org/tracker/CVE-2011-3630 https://www.openwall.com/lists/oss-security/2011/10/20/6 • CWE-787: Out-of-bounds Write •
