https://notcve.org/view.php?id=CVE-2020-8597
eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eap_request and eap_response functions. El archivo eap.c en pppd en ppp versiones 2.4.2 hasta 2.4.8, presenta un desbordamiento del búfer de rhostname en las funciones eap_request y eap_response. A buffer overflow flaw was found in the ppp package in versions 2.4.2 through 2.4.8. The bounds check for the rhostname was improperly constructed in the EAP request and response functions which could allow a buffer overflow to occur. Data confidentiality and integrity, as well as system availability, are all at risk with this vulnerability. • https://github.com/dointisme/CVE-2020-8597 https://github.com/WinMin/CVE-2020-8597 https://github.com/lakwsh/CVE-2020-8597 https://github.com/Dilan-Diaz/Point-to-Point-Protocol-Daemon-RCE-Vulnerability-CVE-2020-8597- http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00006.html http://packetstormsecurity.com/files/156662/pppd-2.4.8-Buffer-Overflow.html http://packetstormsecurity.com/files/156802/pppd-2.4.8-Buffer-Overflow.html http://seclists.org/fulldisclosure/2020/Mar/ • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVSS: 6.5EPSS: 0%CPEs: 897EXPL: 0CVE-2020-0549 – hw: L1D Cache Eviction Sampling
https://notcve.org/view.php?id=CVE-2020-0549
Cleanup errors in some data cache evictions for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Unos errores de limpieza en algunos desalojos de caché de datos para algunos procesadores Intel(R), pueden permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio del acceso local. A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents (which were expected to be blank) can be inferred using MDS or TAA style attack methods to allow a local attacker to infer fill buffer values. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00016.html https://kc.mcafee.com/corporate/index?page=content&id=SB10318 https://lists.debian.org/debian-lts-announce/2020/06/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DT2VKDMQ3I37NBNJ256A2EXR7OJHXXKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/T5OUM24ZC43G4IDT3JUCIHJTSDXJSK6Y https://security.netapp.com/advisory/ntap-20200210-0004 https://usn.ubunt • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-404: Improper Resource Shutdown or Release •
CVSS: 4.7EPSS: 0%CPEs: 74EXPL: 0CVE-2019-15795 – python-apt uses MD5 for validation
https://notcve.org/view.php?id=CVE-2019-15795
python-apt only checks the MD5 sums of downloaded files in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py in version 1.9.0ubuntu1 and earlier. This allows a man-in-the-middle attack which could potentially be used to install altered packages and has been fixed in versions 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5. Python-apt solo comprueba las cantidades MD5 de los archivos descargados en las funciones "Version.fetch_binary()" y "Version.fetch_source()" del archivo apt/package.py en la versión 1.9.0ubuntu1 y anteriores. Esto permite un ataque de tipo man-in-the-middle que podría ser usado para instalar paquetes alterados y ha sido corregido en las versiones 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9. 3.5ubuntu3+esm2, y 0.8.3ubuntu7.5. • https://usn.ubuntu.com/4247-1 https://usn.ubuntu.com/4247-3 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
