CVSS: 6.1EPSS: 0%CPEs: 21EXPL: 0CVE-2024-20506 – ClamAV Privilege Handling Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2024-20506
A vulnerability in the ClamD service module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and 0.103.11 and all prior versions could allow an authenticated, local attacker to corrupt critical system files. The vulnerability is due to allowing the ClamD process to write to its log file while privileged without checking if the logfile has been replaced with a symbolic link. An attacker could exploit this vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by appending ClamD log messages after restart. • https://blog.clamav.net/2024/09/clamav-141-132-107-and-010312-security.html •

https://notcve.org/view.php?id=CVE-2024-20505
A vulnerability in the PDF parsing module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and 0.103.11 and all prior versions could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an out of bounds read. An attacker could exploit this vulnerability by submitting a crafted PDF file to be scanned by ClamAV on an affected device. An exploit could allow the attacker to terminate the scanning process. • https://blog.clamav.net/2024/09/clamav-141-132-107-and-010312-security.html •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-20380 – ClamAV HTML Parser Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2024-20380
A vulnerability in the HTML parser of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an issue in the C to Rust foreign function interface. An attacker could exploit this vulnerability by submitting a crafted file containing HTML content to be scanned by ClamAV on an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software. Una vulnerabilidad en el analizador HTML de ClamAV podría permitir que un atacante remoto no autenticado provoque una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad se debe a un problema en la interfaz de función externa de C a Rust. • https://blog.clamav.net/2024/04/clamav-131-123-106-patch-versions.html • CWE-475: Undefined Behavior for Input to API •
CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 0CVE-2024-20328 – ClamAV VirusEvent File Processing Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2024-20328
A vulnerability in the VirusEvent feature of ClamAV could allow a local attacker to inject arbitrary commands with the privileges of the application service account.The vulnerability is due to unsafe handling of file names. A local attacker could exploit this vulnerability by supplying a file name containing command-line sequences. When processed on a system using configuration options for the VirusEvent feature, the attacker could cause the application to execute arbitrary commands. ClamAV has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. • https://blog.clamav.net/2023/11/clamav-130-122-105-released.html • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 9.8EPSS: 0%CPEs: 18EXPL: 0CVE-2023-20032
https://notcve.org/view.php?id=CVE-2023-20032
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code. This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write. An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the ClamAV scanning process, or else crash the process, resulting in a denial of service (DoS) condition.
