CVSS: 9.8EPSS: 0%CPEs: 6EXPL: 1CVE-2019-17041 – rsyslog: heap-based overflow in contrib/pmaixforwardedfrom/pmaixforwardedfrom.c
https://notcve.org/view.php?id=CVE-2019-17041
An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap overflow in the parser for AIX log messages. The parser tries to locate a log message delimiter (in this case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. • https://github.com/Resery/CVE-2019-17041 http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00032.html https://github.com/rsyslog/rsyslog/blob/v8-stable/ChangeLog https://github.com/rsyslog/rsyslog/pull/3884 https://lists.debian.org/debian-lts-announce/2021/11/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPNCHI7X2IEXRH6RYD6IDPR4PLB5RPC7 https://lists.fed • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-16881
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 •

https://notcve.org/view.php?id=CVE-2018-1000140
rsyslog librelp version 1.2.14 and earlier contains a Buffer Overflow vulnerability in the checking of x509 certificates from a peer that can result in Remote code execution. This attack appear to be exploitable a remote attacker that can connect to rsyslog and trigger a stack buffer overflow by sending a specially crafted x509 certificate. rsyslog librelp en versiones 1.2.14 y anteriores contiene una vulnerabilidad de desbordamiento de búfer en la verificación de certificados x509 desde un peer que puede resultar en la ejecución remota de código. Parece que este ataque puede ser explotable debido a que un atacante remoto puede conectarse a rsyslog y desencadena un desbordamiento de búfer basado en pila mediante el envío de un certificado x509 especialmente manipulado. A stack-based buffer overflow was found in the way librelp parses X.509 certificates. By connecting or accepting connections from a remote peer, an attacker may use a specially crafted X.509 certificate to exploit this flaw and potentially execute arbitrary code. • https://github.com/s0/rsyslog-librelp-CVE-2018-1000140 https://github.com/s0/rsyslog-librelp-CVE-2018-1000140-fixed http://packetstormsecurity.com/files/172829/librelp-Remote-Code-Execution.html https://access.redhat.com/errata/RHSA-2018:1223 https://access.redhat.com/errata/RHSA-2018:1225 https://access.redhat.com/errata/RHSA-2018:1701 https://access.redhat.com/errata/RHSA-2018:1702 https://access.redhat.com/errata/RHSA-2018:1703 https://access.redhat.com/errata/RHSA-2018:1704 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •
