In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components. En Dovecot, en versiones anteriores a la 2.2.36.3 y en las 2.3.x anteriores a la 2.3.5.1, un atacante local puede provocar un desbordamiento de búfer en el proceso "indexer-worker", que se podría utilizar para elevar a root. Esto ocurre debido a la falta de comprobaciones en los componentes fts y pop3-uidl. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00067.html http://www.openwall.com/lists/oss-security/2019/03/28/1 http://www.securityfocus.com/bid/107672 https://dovecot.org/list/dovecot-news/2019-March/000403.html https://dovecot.org/security.html https://lists.debian.org/debian-lts-announce/2019/03/msg00038.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.o • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-284: Improper Access Control •

The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. El búfer del socket SCTP utilizado por una aplicación de espacio de usuario no es tenido en cuenta por el subsistema de cgroups. Un atacante podría explotar este error para lanzar un ataque de denegación de servicio. • https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3874 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://security.netapp.com/advisory/ntap-20190411-0003 https://usn.ubuntu.com/3979-1 https://usn.ubuntu.com/3980-1 https://usn.ubuntu.com/3980-2 https://usn.ubuntu.com/3981-1 https://usn.ubuntu.com/3981-2 https://usn.ubuntu.com/398 • CWE-400: Uncontrolled Resource Consumption •

urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call. urllib en Python, en versiones 2.x hasta la 2.7.16, soporta el esquema local_file:, lo que facilita que los atacantes remotos omitan los mecanismos de protección que ponen en lista negra los URI file:, tal y como queda demostrado con una llamada urllib.urlopen('local_file:///etc/passwd'). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00050.html http://packetstormsecurity.com/files/154927/Slackware-Security-Advisory-python-Updates.html http://www.securityfocus.com/bid/107549 https://access.redhat.com/errata/RHSA-2019:1700 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3335 https://access.redhat.com/errata/RHSA-2019:3520 https://bugs.python.o • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-749: Exposed Dangerous Method or Function •

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4. Una vulnerabilidad en los filtros seccomp de Canonical snapd anterior a la versión 2.37.4 permite un ajuste de modo estricto para introducir caracteres en un terminal en un host de 64 bits. Las reglas de seccomp se generaron para que coincidieran con los comandos ioctl (2) de 64 bits en una plataforma de 64 bits; sin embargo, el kernel de Linux solo utiliza los bits inferiores 32 para determinar qué comandos ioctl (2) ejecutar. • https://www.exploit-db.com/exploits/46594 https://usn.ubuntu.com/3917-1 • CWE-628: Function Call with Incorrectly Specified Arguments •
