CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 1CVE-2019-1787 – Clam AntiVirus PDF Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1787
A vulnerability in the Portable Document Format (PDF) scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of proper data handling mechanisms within the device buffer while indexing remaining file data on an affected device. An attacker could exploit this vulnerability by sending crafted PDF files to an affected device. A successful exploit could allow the attacker to cause a heap buffer out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device. Una vulnerabilidad en la funcionalidad de escaneo del PDF (Portable Document Format) en las versiones de software 0.101.1 y anteriores de Clam AntiVirus (ClamAV), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00064.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12181 https://lists.debian.org/debian-lts-announce/2019/04/msg00019.html https://security.gentoo.org/glsa/201904-12 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2018-15378 – Clam AntiVirus unmew11() Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15378
A vulnerability in ClamAV versions prior to 0.100.2 could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to an error related to the MEW unpacker within the "unmew11()" function (libclamav/mew.c), which can be exploited to trigger an invalid read memory access via a specially crafted EXE file. Una vulnerabilidad en las versiones anteriores a la 0.100.2 de ClamAV podría permitir que un atacante provoque una condición de denegación de servicio (DoS). La vulnerabilidad se debe a un error relacionado con el desempaquetador MEW en la función "unmew11()" en libclamav/mew.c, que podría explicarse para desencadenar un acceso inválido de lectura a la memoria mediante un archivo EXE especialmente manipulado. • https://bugzilla.clamav.net/show_bug.cgi?id=12170 https://lists.debian.org/debian-lts-announce/2018/10/msg00014.html https://secuniaresearch.flexerasoftware.com/advisories/83000 https://security.gentoo.org/glsa/201904-12 https://usn.ubuntu.com/3789-1 https://usn.ubuntu.com/3789-2 https://www.flexera.com/company/secunia-research/advisories/SR-2018-23.html • CWE-125: Out-of-bounds Read •

ClamAV before 0.100.1 has an HWP integer overflow with a resultant infinite loop via a crafted Hangul Word Processor file. This is in parsehwp3_paragraph() in libclamav/hwp.c. ClamAV en versiones anteriores a la 0.100.1 tiene un desbordamiento de enteros HWP con un bucle infinito resultante mediante un archivo Hangul Word Processor manipulado.

ClamAV before 0.100.1 lacks a PDF object length check, resulting in an unreasonably long time to parse a relatively small file. ClamAV en versiones anteriores a la 0.100.1 carece de una comprobación de longitud de objeto, lo que resulta en un tiempo demasiado largo para analizar un archivo relativamente pequeño. • http://www.securitytracker.com/id/1041367 https://blog.clamav.net/2018/07/clamav-01001-has-been-released.html https://lists.debian.org/debian-lts-announce/2018/08/msg00020.html https://security.gentoo.org/glsa/201904-12 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-0202
clamscan in ClamAV before 0.99.4 contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause an out-of-bounds read when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition. This concerns pdf_parse_array and pdf_parse_string in libclamav/pdfng.c. • https://github.com/jaychowjingjie/CVE-2018-0202 https://bugzilla.clamav.net/show_bug.cgi?id=11973 https://bugzilla.clamav.net/show_bug.cgi?id=11980 https://lists.debian.org/debian-lts-announce/2018/03/msg00011.html https://security.gentoo.org/glsa/201804-16 https://usn.ubuntu.com/3592-1 https://usn.ubuntu.com/3592-2 • CWE-125: Out-of-bounds Read •
