CVSS: 7.5EPSS: 1%CPEs: 2EXPL: 0CVE-2019-15890 – QEMU: Slirp: use-after-free during packet reassembly
https://notcve.org/view.php?id=CVE-2019-15890
libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c. libslirp versión 4.0.0, como es usado en QEMU versión 4.1.0, presenta un uso de la memoria previamente liberada en la función ip_reass en el archivo ip_input.c. A use-after-free issue was found in the SLiRP networking implementation of the QEMU emulator. The issue occurs in ip_reass() routine while reassembling incoming packets, if the first fragment is bigger than the m->m_dat[] buffer. A user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00034.html http://www.openwall.com/lists/oss-security/2019/09/06/3 https://access.redhat.com/errata/RHSA-2020:0775 https://gitlab.freedesktop.org/slirp/libslirp/commit/c5927943 https://lists.debian.org/debian-lts-announce/2019/09/msg00021.html https://seclists.org/bugtraq/2020/Feb/0 https://usn.ubuntu.com/4191-1 https://usn.ubuntu.com/4191-2 https://www.debian.org/security/2020/dsa-4616 https://ac • CWE-416: Use After Free •

The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue **EN DISPUTA** El comando QMP guest_exec en QEMU versión 4.0.0 y anteriores es propenso a la inyección de comandos del sistema operativo, lo que permite al atacante remoto lograr la ejecución de código, una denegación de servicio, o la divulgación de información mediante el envío de un comando QMP manipulado al servidor de escucha. Nota: Está siendo discutida por no ser un problema ya que la interfaz -qmp de QEMU está destinada a ser utilizada por usuarios de confianza. Si uno puede acceder a esta interfaz a través de un socket TCP abierto a Internet, entonces es un problema de configuración inseguro. • https://fakhrizulkifli.github.io/posts/2019/06/06/CVE-2019-12929 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-668: Exposure of Resource to Wrong Sphere •
