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') •

In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially. En el archivo xml.rs en GNOME librsvg versiones anteriores a 2.46.2, un archivo SVG diseñado con patrones anidados puede causar una denegación de servicio cuando es pasado a la biblioteca para su procesamiento. El atacante construye elementos de patrón para que el número de objetos renderizados finales aumente exponencialmente. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00024.html https://gitlab.gnome.org/GNOME/librsvg/issues/515 https://lists.debian.org/debian-lts-announce/2020/07/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6IOHSO6BUKC6I66J5PZOMAGFVJ66ZS57 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X3B5RWJQD5LA45MYLLR55KZJOJ5NVZGP https://security.netapp.com/advisory/ntap-20221111-0004 https://usn.ubuntu.com/443 • CWE-400: Uncontrolled Resource Consumption •

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 •

https://notcve.org/view.php?id=CVE-2019-20421
In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file. En la función Jp2Image::readMetadata() en el archivo jp2image.cpp en Exiv2 versión 0.27.2, un archivo de entrada puede generar un bucle infinito y suspensión, con un alto consumo de CPU. Los atacantes remotos podrían aprovechar esta vulnerabilidad para causar una denegación de servicio por medio de un archivo diseñado. A denial of service vulnerability was found in exiv2 in the way JPEG 2000 (JP2) metadata was read when processing an image file. • https://github.com/Exiv2/exiv2/commit/a82098f4f90cd86297131b5663c3dec6a34470e8 https://github.com/Exiv2/exiv2/issues/1011 https://lists.debian.org/debian-lts-announce/2021/08/msg00028.html https://usn.ubuntu.com/4270-1 https://www.debian.org/security/2021/dsa-4958 https://access.redhat.com/security/cve/CVE-2019-20421 https://bugzilla.redhat.com/show_bug.cgi?id=1800472 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
