CVSS: 7.5EPSS: 1%CPEs: 20EXPL: 1CVE-2020-25645 – kernel: Geneve/IPsec traffic may be unencrypted between two Geneve endpoints
https://notcve.org/view.php?id=CVE-2020-25645
A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. Se encontró un fallo en el kernel de Linux en versiones anteriores a 5.9-rc7. El tráfico entre dos endpoints Geneve puede no estar cifrado cuando IPsec está configurado para cifrar el tráfico para el puerto UDP específico usado por el túnel GENEVE, permitiendo a cualquier persona entre los dos endpoints leer el tráfico sin cifrar. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00042.html http://packetstormsecurity.com/files/161229/Kernel-Live-Patch-Security-Notice-LSN-0074-1.html https://bugzilla.redhat.com/show_bug.cgi?id=1883988 https://lists.debian.org/debian-lts-announce/2020/10/msg00028.html https://lists.debian.org/debian-lts-announce/2020/12/msg00027.html https://security.netapp.com/advisory/ntap-20201103-0004 https://ww • CWE-319: Cleartext Transmission of Sensitive Information •
CVSS: 6.6EPSS: 0%CPEs: 15EXPL: 0CVE-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') •
CVSS: 5.3EPSS: 0%CPEs: 17EXPL: 1CVE-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 •

https://notcve.org/view.php?id=CVE-2020-26137
urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this is similar to CVE-2020-26116. urllib3 versiones anteriores a 1.25.9, permite una inyección de CRLF si el atacante controla el método de petición HTTP, como es demostrado al insertar caracteres de control CR y LF en el primer argumento de la función putrequest(). NOTA: esto es similar a CVE-2020-26116 A flaw was found in python-urllib3. The HTTPConnection.request() does not properly validate CRLF sequences in the HTTP request method, potentially allowing manipulation of the request by injecting additional HTTP headers. The highest threat from this vulnerability is to confidentiality and integrity. • https://bugs.python.org/issue39603 https://github.com/urllib3/urllib3/commit/1dd69c5c5982fae7c87a620d487c2ebf7a6b436b https://github.com/urllib3/urllib3/pull/1800 https://lists.debian.org/debian-lts-announce/2021/06/msg00015.html https://lists.debian.org/debian-lts-announce/2023/10/msg00012.html https://usn.ubuntu.com/4570-1 https://www.oracle.com/security-alerts/cpujul2022.html https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2020-26137 https& • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
