CVSS: 7.5EPSS: 2%CPEs: 5EXPL: 1CVE-2019-7303 – Snapd seccomp filter TIOCSTI ioctl bypass
https://notcve.org/view.php?id=CVE-2019-7303
A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4. Una vulnerabilidad en los filtros seccomp de Canonical snapd anterior a la versión 2.37.4 permite un ajuste de modo estricto para introducir caracteres en un terminal en un host de 64 bits. Las reglas de seccomp se generaron para que coincidieran con los comandos ioctl (2) de 64 bits en una plataforma de 64 bits; sin embargo, el kernel de Linux solo utiliza los bits inferiores 32 para determinar qué comandos ioctl (2) ejecutar. • https://www.exploit-db.com/exploits/46594 https://usn.ubuntu.com/3917-1 • CWE-628: Function Call with Incorrectly Specified Arguments •

An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation. Se ha descubierto un problema por el cual una dirección proporcionada con access_ok() no se comprueba en i915_gem_execbuffer2_ioctl en drivers/gpu/drm/i915/i915_gem_execbuffer.c en el kernel de Linux hasta la versión 4.19.13. Un atacante local puede manipular una llamada de función IOCTL para sobrescribir memoria arbitraria del kernel, lo que resulta en una denegación de servicio (DoS) o el escalado de privilegios. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/gpu/drm/i915/i915_gem_execbuffer.c http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://www.openwall.com/lists/oss-security/2019/01/23/6 http://www.securityfocus.com/bid/106748 https://access.redhat.com/security/cve/cve-2018-20669 https://security.netapp.com/advisory/ntap-20190404-0002 https://support.f5.com/csp/article/K32059550 https://usn.ubuntu.com/4485-1 • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2019-6778 – QEMU: slirp: heap buffer overflow in tcp_emu()
https://notcve.org/view.php?id=CVE-2019-6778
In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow. En QEMU 3.0.0, tcp_emu en slirp/tcp_subr.c tiene un desbordamiento de búfer basado en memoria dinámica (heap). A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. It occurs in tcp_emu() routine while emulating the Identification protocol and copying message data to a socket buffer. A user or process could use this flaw to crash the QEMU process on the host resulting in a DoS or potentially executing arbitrary code with privileges of the QEMU process. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00007.html http://www.openwall.com/lists/oss-security/2019/01/24/5 http://www.securityfocus.com/bid/106758 https://access.redhat.com& • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

The XMLTooling library all versions prior to V3.0.4, provided with the OpenSAML and Shibboleth Service Provider software, contains an XML parsing class. Invalid data in the XML declaration causes an exception of a type that was not handled properly in the parser class and propagates an unexpected exception type. La libreria XMLTooling, en todas las versiones anteriores a la V3.0.4, suministrada con el software OpenSAML y Shibboleth Service Provider, contiene una clase de parser XML.
