CVE-2020-14362 – X.Org Server XRecordRegisterClients Integer Underflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-14362
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en X.Org Server versiones anteriores a xorg-x11-server 1.20.9. Un subdesbordamiento de enteros que conlleva a un desbordamiento del búfer de la pila puede conllevar a una vulnerabilidad de escalada de privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1869144 https://lists.x.org/archives/xorg-announce/2020-August/003058.html https://security.gentoo.org/glsa/202012-01 https://usn.ubuntu.com/4488-2 https://www.zerodayinitiative.com/advisories/ZDI-20-1419 https://access.redhat.com/security/cve/CVE-2020-14362 • CWE-191: Integer Underflow (Wrap or Wraparound) •

The intermediate-level directories of the filesystem cache had the system's standard umask rather than 0o077. Se detectó un problema en Django versiones 2.2 anteriores a 2.2.16, versiones 3.0 anteriores a 3.0.10 y versiones 3.1 anteriores a 3.1.1 (cuando es usado Python 3.7+). Los directorios de nivel intermedio de la caché del sistema de archivos tenían la umask estándar del sistema en lugar de 0o077 • https://docs.djangoproject.com/en/dev/releases/security https://groups.google.com/forum/#%21topic/django-announce/Gdqn58RqIDM https://groups.google.com/forum/#%21topic/django-announce/zFCMdgUnutU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F2ZHO3GZCJMP3DDTXCNVFV6ED3W64NAU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OLGFFLMF3X6USMJD7V5F5P4K2WVUTO3T https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/m • CWE-276: Incorrect Default Permissions •

CVE-2020-14364 – QEMU: usb: out-of-bounds r/w access issue while processing usb packets
https://notcve.org/view.php?id=CVE-2020-14364
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. Se encontró un fallo de acceso de lectura/escritura fuera de límites en el emulador USB de QEMU en versiones anteriores a la 5.2.0. Este problema ocurre mientras se procesan paquetes USB de un invitado cuando USBDevice "setup_len" excede su "data_buf [4096]" en las rutinas do_token_in, do_token_out. • https://github.com/gejian-iscas/CVE-2020-14364 https://github.com/y-f00l/CVE-2020-14364 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html https://bugzilla.redhat.com/show_bug.cgi?id=1869201 https://lists.debian.org/debian-lts-announce/2020/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTZQUQ6ZBPMFMNAUQBVJFELYNMUZLL6P https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M52WIRMZL6T • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
