CVSS: 8.1EPSS: 19%CPEs: 6EXPL: 0CVE-2022-24903 – Buffer overflow in TCP syslog server (receiver) components in rsyslog
https://notcve.org/view.php?id=CVE-2022-24903
Rsyslog is a rocket-fast system for log processing. Modules for TCP syslog reception have a potential heap buffer overflow when octet-counted framing is used. This can result in a segfault or some other malfunction. As of our understanding, this vulnerability can not be used for remote code execution. But there may still be a slight chance for experts to do that. • https://github.com/rsyslog/rsyslog/commit/f211042ecbb472f9d8beb4678a65d272b6f07705 https://github.com/rsyslog/rsyslog/security/advisories/GHSA-ggw7-xr6h-mmr8 https://lists.debian.org/debian-lts-announce/2022/05/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMNNXLCU2UORRVSZO24HL4KMVPK5PHVW https://security.netapp.com/advisory/ntap-20221111-0002 https://www.debian.org/security/2022/dsa-5150 https://access.redhat.com/security/cve/CVE-2022-24903 https://bug • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write CWE-1284: Improper Validation of Specified Quantity in Input •

A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable. Se ha detectado una vulnerabilidad de denegación de servicio (DoS) en rsyslog en el módulo imptcp. Un atacante podría enviar un mensaje especialmente manipulado al socket imptcp, lo que conduciría al cierre forzado de rsyslog. • https://access.redhat.com/errata/RHBA-2019:2501 https://access.redhat.com/errata/RHSA-2019:2110 https://access.redhat.com/errata/RHSA-2019:2437 https://access.redhat.com/errata/RHSA-2019:2439 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16881 https://lists.debian.org/debian-lts-announce/2022/05/msg00028.html https://access.redhat.com/security/cve/CVE-2018-16881 https://bugzilla.redhat.com/show_bug.cgi?id=1658366 • CWE-190: Integer Overflow or Wraparound •

The zmq3 input and output modules in rsyslog before 8.28.0 interpreted description fields as format strings, possibly allowing a format string attack with unspecified impact. Los módulos de entrada y salida de zmq3 en versiones de rsyslog anteriores a 8.28.0 interpretaban campos de descripción como cadenas de formato, lo que podía dar lugar a un ataque de tipo “format string” y causar un impacto no especificado. • https://github.com/rsyslog/rsyslog/blob/master/ChangeLog https://github.com/rsyslog/rsyslog/commit/062d0c671a29f7c6f7dff4a2f1f35df375bbb30b https://github.com/rsyslog/rsyslog/pull/1565 • CWE-134: Use of Externally-Controlled Format String •

Integer overflow in rsyslog before 7.6.7 and 8.x before 8.4.2 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash) via a large priority (PRI) value. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3634. Desbordamiento de enteros en rsyslog anterior a 7.6.7 y 8.x anterior a 8.4.2 y sysklogd 1.5 y anteriores permite a atacantes remotos causar una denegación de servicio (caída) a través de un valor de prioridad (PRI) grande. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-3634. • http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00005.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00020.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00021.html http://secunia.com/advisories/61494 http://www.debian.org/security/2014/dsa-3047 http://www.openwall.com/lists/oss-security/2014/09/30/15 http://www.openwall.com/lists/oss-security/2014/10/03/1 http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http: • CWE-189: Numeric Errors •
CVSS: 7.5EPSS: 24%CPEs: 25EXPL: 1CVE-2014-3634 – rsyslog: remote syslog PRI vulnerability
https://notcve.org/view.php?id=CVE-2014-3634
rsyslog before 7.6.6 and 8.x before 8.4.1 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash), possibly execute arbitrary code, or have other unspecified impact via a crafted priority (PRI) value that triggers an out-of-bounds array access. rsyslog anterior a 7.6.6 y 8.x anterior a 8.4.1 y sysklogd 1.5 y anteriores permiten a atacantes remotos causar una denegación de servicio (caída), posiblemente ejecutar código arbitrario o tener otro impacto no especificado a través de un valor de prioridad (PRI) manipulado que provoca un acceso a array fuera de rango. A flaw was found in the way rsyslog handled invalid log message priority values. In certain configurations, a local attacker, or a remote attacker able to connect to the rsyslog port, could use this flaw to crash the rsyslog daemon or, potentially in rsyslog 7.x, execute arbitrary code as the user running the rsyslog daemon. • http://advisories.mageia.org/MGASA-2014-0411.html http://linux.oracle.com/errata/ELSA-2014-1654 http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00005.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00020.html http://lists.opensuse.org/opensuse-updates/2014-10/msg00021.html http://rhn.redhat.com/errata/RHSA-2014-1397.html http://rhn.redhat.com/errata/RHSA-2014-1654.html http://rhn.redhat.com/errata/RHSA-2014-1671.html http://secunia.com/advisories/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
