A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhost_crypto has validated it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en dpdk en versiones anteriores a 18.11.10 y anteriores a 19.11.5. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00006.html http://www.openwall.com/lists/oss-security/2021/01/04/1 http://www.openwall.com/lists/oss-security/2021/01/04/2 http://www.openwall.com/lists/oss-security/2021/01/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1879468 https://usn.ubuntu.com/4550-1 https://www.openwall.com/lists/oss-security/2020/09/28/3 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period. Un subdesbordamiento de enteros en dpdk versiones anteriores a 18.11.10 y anteriores a 19.11.5 en la función "move_desc" puede conllevar a que sean consumidos grandes cantidades de ciclos de CPU en un bucle de larga ejecución. Un atacante podría causar que "move_desc" se atasque en un bucle de iteración de 4.294.967.295 conteos. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00006.html http://www.openwall.com/lists/oss-security/2021/01/04/1 http://www.openwall.com/lists/oss-security/2021/01/04/2 http://www.openwall.com/lists/oss-security/2021/01/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1879473 https://usn.ubuntu.com/4550-1 https://www.openwall.com/lists/oss-security/2020/09/28/3 • CWE-191: Integer Underflow (Wrap or Wraparound) •

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copy_data function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhost_crypto application. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en dpdk en versiones anteriores a 18.11.10 y anteriores a 19.11.5. Una comprobación de límites fallida en la función copy_data conlleva a un desbordamiento del búfer que permite a un atacante en una máquina virtual escribir datos arbitrarios en cualquier dirección en la aplicación vhost_crypto. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00006.html http://www.openwall.com/lists/oss-security/2021/01/04/1 http://www.openwall.com/lists/oss-security/2021/01/04/2 http://www.openwall.com/lists/oss-security/2021/01/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1879466 https://www.openwall.com/lists/oss-security/2020/09/28/3 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2020-26117
In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception.
