CVE-2020-3341 – ClamAV PDF Parsing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3341
A vulnerability in the PDF archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.101 - 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a stack buffer overflow read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de archivos PDF en Clam AntiVirus (ClamAV) Software versiones 0.101 hasta 0.102.2, podría permitir a un atacante no autenticado remoto causar una condición de denegación de servicio sobre un dispositivo afectado. • https://blog.clamav.net/2020/05/clamav-01023-security-patch-released.html https://lists.debian.org/debian-lts-announce/2020/05/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BMTC7I5LGY4FCIZLHPNC4WWC6VNLFER https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L5YWYT27SBTV4RZSGFHIQUI4LQVFASWS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ROBJOGJOT44MVDX7RQEACYHQN4LYW5RK https://usn.ubuntu.com/ • CWE-20: Improper Input Validation •

CVE-2018-1285
https://notcve.org/view.php?id=CVE-2018-1285
Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files. Apache log4net versiones anteriores a 2.0.10, no deshabilita las entidades externas XML cuando analiza los archivos de configuración de log4net. Esto permite realizar ataques basados en XXE en aplicaciones que aceptan archivos de configuración log4net controlados por el atacante • https://issues.apache.org/jira/browse/LOG4NET-575 https://lists.apache.org/thread.html/r00b16ac5e0bbf7009a0d167ed58f3f94d0033b0f4b3e3d5025cc4872%40%3Cdev.logging.apache.org%3E https://lists.apache.org/thread.html/r33564de316d4e4ba0fea1d4d079e62cde1ffe64369c1157243d840d9%40%3Cdev.logging.apache.org%3E https://lists.apache.org/thread.html/r525cbbd7db0aef4a114cf60de8439aa285decc34904d42a7f14f39c3%40%3Cdev.logging.apache.org%3E https://lists.apache.org/thread.html/r6543acafca3e2d24ff4b0c364a91540cb9378977ffa8d37a03ab4b0f%40%3Cdev.logging.apache.org%3E https://lists.apache.or • CWE-611: Improper Restriction of XML External Entity Reference •
CVE-2020-12770 – kernel: sg_write function lacks an sg_remove_request call in a certain failure case
https://notcve.org/view.php?id=CVE-2020-12770
An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. Se detectó un problema en el kernel de Linux versiones hasta 5.6.11. La función sg_write, carece de una llamada a sg_remove_request en un determinado caso de fallo, también se conoce como CID-83c6f2390040. A vulnerability was found in sg_write in drivers/scsi/sg.c in the SCSI generic (sg) driver subsystem. This flaw allows an attacker with local access and special user or root privileges to cause a denial of service if the allocated list is not cleaned with an invalid (Sg_fd * sfp) pointer at the time of failure, also possibly causing a kernel internal information leak problem. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=83c6f2390040f188cc25b270b4befeb5628c1aee https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ES5C6ZCMALBEBMKNNCTBSLLSYGFZG3FF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedora • CWE-416: Use After Free •
CVE-2020-12762 – libfastjson: integer overflow and out-of-bounds write via a large JSON file
https://notcve.org/view.php?id=CVE-2020-12762
json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend. json-c versiones hasta 0.14, presenta un desbordamiento de enteros y una escritura fuera de límites por medio de un archivo JSON grande, como es demostrado por la función printbuf_memappend. A flaw was found in json-c. In printbuf_memappend, certain crafted values can overflow the memory allowing an attacker to write past the memory boundary. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://github.com/json-c/json-c/pull/592 https://github.com/rsyslog/libfastjson/issues/161 https://lists.debian.org/debian-lts-announce/2020/05/msg00032.html https://lists.debian.org/debian-lts-announce/2020/05/msg00034.html https://lists.debian.org/debian-lts-announce/2020/07/msg00031.html https://lists.debian.org/debian-lts-announce/2023/06/msg00023.html https://lists.fedoraproject.org/archives/list/package-annou • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
