CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 1CVE-2020-1983 – libslirp: use after free vulnerability cause a denial of service.
https://notcve.org/view.php?id=CVE-2020-1983
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service. Una vulnerabilidad de uso de la memoria previamente liberada en la función ip_reass() en el archivo ip_input.c de libslirp versiones 4.2.0 y anteriores permite que paquetes especialmente diseñados causen una denegación de servicio. A use-after-free flaw was found in the SLiRP networking implementation of the QEMU emulator. Specifically, this flaw occurs in the ip_reass() routine while reassembling incoming IP fragments whose combined size is bigger than 65k. This flaw allows an attacker to crash the QEMU process on the host, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00001.html https://gitlab.freedesktop.org/slirp/libslirp/-/commit/9ac0371bb8c0a40f5d9f82a1c25129660e81df04 https://gitlab.freedesktop.org/slirp/libslirp/-/issues/20 https://lists.debian.org/debian-lts-announce/2020/06/msg00032.html https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-416: Use After Free •

An exploitable denial of service vulnerability exists in the GstRTSPAuth functionality of GStreamer/gst-rtsp-server 1.14.5. A specially crafted RTSP setup request can cause a null pointer deference resulting in denial-of-service. An attacker can send a malicious packet to trigger this vulnerability. Se presenta una vulnerabilidad de denegación de servicio explotable en la funcionalidad GstRTSPAuth de GStreamer/gst-rtsp-server versión 1.14.5. Una petición de configuración RTSP especialmente diseñada puede causar una deferencia del puntero null resultando en una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00029.html https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/-/commit/44ccca3086dd81081d72ca0b21d0ecdde962fb1a https://security.gentoo.org/glsa/202009-05 https://www.talosintelligence.com/vulnerability_reports/TALOS-2020-1018 • CWE-476: NULL Pointer Dereference CWE-690: Unchecked Return Value to NULL Pointer Dereference •

An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because the hostname check operates on uninitialized memory. The outcome is that a valid certificate is never accepted (only a malformed certificate may be accepted). Se detectó un problema en openfortivpn versión 1.11.0, cuando se usaba con OpenSSL versiones 1.0.2 o posteriores, en el archivo tunnel.c, maneja inapropiadamente la comprobación del certificado porque la verificación del nombre de host funciona en la memoria no inicializada. El resultado es que un certificado válido nunca es aceptado (solo puede ser aceptado un certificado malformado). • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00011.html https://github.com/adrienverge/openfortivpn/commit/9eee997d599a89492281fc7ffdd79d88cd61afc3 https://github.com/adrienverge/openfortivpn/commit/cd9368c6a1b4ef91d77bb3fdbe2e5bc34aa6f4c4 https://github.com/adrienverge/openfortivpn/issues/536 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CKNKSGBVYGRRVRLFEFBEKUEJYJR5LWOF https://lists.fedoraproject.org/archives/l • CWE-295: Improper Certificate Validation CWE-908: Use of Uninitialized Resource •
