CVE-2020-14355 – spice: multiple buffer overflow vulnerabilities in QUIC decoding code
https://notcve.org/view.php?id=CVE-2020-14355
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution. Se encontraron múltiples vulnerabilidades de desbordamiento de búfer en el proceso de decodificación de imágenes QUIC del sistema de visualización remota SPICE, versiones anteriores a spice-0.14.2-1. Tanto el cliente SPICE (spice-gtk) como el servidor están afectados por estos defectos. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00001.html https://bugzilla.redhat.com/show_bug.cgi?id=1868435 https://lists.debian.org/debian-lts-announce/2020/11/msg00001.html https://lists.debian.org/debian-lts-announce/2020/11/msg00002.html https://usn.ubuntu.com/4572-1 https://usn.ubuntu.com/4572-2 https://www.debian.org/security/2020/dsa-4771 https://www.openwall.com/lists/oss • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2020-25641 – kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS
https://notcve.org/view.php?id=CVE-2020-25641
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

CVE-2020-7070 – PHP parses encoded cookie names so malicious `__Host-` cookies can be sent
https://notcve.org/view.php?id=CVE-2020-7070
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-8184 for more information. En PHP versiones 7.2.x por debajo de 7.2.34, versiones 7.3.x por debajo de 7.3.23 y versiones 7.4.x por debajo de 7.4.11, cuando PHP procesa valores de cookies HTTP entrantes, los nombres de las cookies se decodifican de la URL. Esto puede conllevar a que las cookies con prefijos como __Host se confundan con las cookies que decodifican dicho prefijo, lo que conlleva a que un atacante pueda falsificar una cookie que se supone que es segura. • http://cve.circl.lu/cve/CVE-2020-8184 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00067.html https://bugs.php.net/bug.php?id=79699 https://hackerone.com/reports/895727 https://lists.debian.org/debian-lts-announce/2020/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7EVDN7D3IB4EAI4D3ZOM2OJKQ5SD7K4E https://lists.fedoraproject.org/archives/list/ • CWE-20: Improper Input Validation CWE-565: Reliance on Cookies without Validation and Integrity Checking •
CVE-2020-7069 – Wrong ciphertext/tag in AES-CCM encryption for a 12 bytes IV
https://notcve.org/view.php?id=CVE-2020-7069
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data. En PHP versiones 7.2.x por debajo de 7.2.34, versiones 7.3.x por debajo de 7.3.23 y versiones 7.4.x por debajo de 7.4.11, cuando el modo AES-CCM es usado con la función openssl_encrypt() con 12 bytes IV, solo los primeros 7 bytes del IV está actualmente usado. Esto puede conllevar a una disminución de seguridad y datos de cifrado incorrectos • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00067.html https://bugs.php.net/bug.php?id=79601 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7EVDN7D3IB4EAI4D3ZOM2OJKQ5SD7K4E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2J3ZZDHCSX65T5QWV4AHBN7MOJXBEKG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R • CWE-20: Improper Input Validation CWE-326: Inadequate Encryption Strength •
CVE-2020-14377
https://notcve.org/view.php?id=CVE-2020-14377
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability. • 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=1879472 https://usn.ubuntu.com/4550-1 https://www.openwall.com/lists/oss-security/2020/09/28/3 • CWE-125: Out-of-bounds Read •
