CVE-2018-1000140 – librelp: Stack-based buffer overflow in relpTcpChkPeerName function in src/tcp.c
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 •
