Multiple unspecified vulnerabilities in ClamAV before 0.94 have unknown impact and attack vectors related to file descriptor leaks on the "error path" in (1) libclamav/others.c and (2) libclamav/sis.c.
CVE-2008-6680 1 Clamav 1 Clamav 2025-04-09 5.0 MEDIUM N/A
libclamav/pe.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (crash) via a crafted EXE file that triggers a divide-by-zero error.

Heap-based buffer overflow in the pefromupx function in libclamav/upx.c in Clam AntiVirus (ClamAV) 0.81 through 0.88.3 allows remote attackers to execute arbitrary code via a crafted UPX packed file containing sections with large rsize values.
CVE-2006-1615 1 Clamav 1 Clamav 2025-04-03 10.0 HIGH N/A
Multiple format string vulnerabilities in the logging code in Clam AntiVirus (ClamAV) before 0.88.1 might allow remote attackers to execute arbitrary code. NOTE: as of 20060410, it is unclear whether this is a vulnerability, as there is some evidence that the arguments are actually being sanitized properly.
CVE-2024-20506 1 Clamav 1 Clamav 2025-03-25 N/A 6.1 MEDIUM
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.
CVE-2024-20505 1 Clamav 1 Clamav 2025-03-25 N/A 4.0 MEDIUM
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.
CVE-2023-20052 3 Cisco, Clamav, Stormshield 4 Secure Endpoint, Secure Endpoint Private Cloud, Clamav and 1 more 2024-11-21 N/A 5.3 MEDIUM
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG 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 access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.
CVE-2023-20032 3 Cisco, Clamav, Stormshield 5 Secure Endpoint, Secure Endpoint Private Cloud, Web Security Appliance and 2 more 2024-11-21 N/A 9.8 CRITICAL
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. For a description of this vulnerability, see the ClamAV blog ["https://blog.clamav.net/"].
CVE-2022-20803 1 Clamav 1 Clamav 2024-11-21 N/A 8.6 HIGH
A vulnerability in the OLE2 file parser of Clam AntiVirus (ClamAV) versions 0.104.0 through 0.104.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device.The vulnerability is due to incorrect use of the realloc function that may result in a double-free. An attacker could exploit this vulnerability by submitting a crafted OLE2 file to be scanned by ClamAV on the affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition.
CVE-2022-20796 4 Cisco, Clamav, Debian and 1 more 4 Secure Endpoint, Clamav, Debian Linux and 1 more 2024-11-21 4.9 MEDIUM 6.5 MEDIUM
On May 4, 2022, the following vulnerability in the ClamAV scanning library versions 0.103.5 and earlier and 0.104.2 and earlier was disclosed: A vulnerability in Clam AntiVirus (ClamAV) versions 0.103.4, 0.103.5, 0.104.1, and 0.104.2 could allow an authenticated, local attacker to cause a denial of service condition on an affected device. For a description of this vulnerability, see the ClamAV blog.
CVE-2022-20792 1 Clamav 1 Clamav 2024-11-21 N/A 7.8 HIGH
A vulnerability in the regex module used by the signature database load module of Clam AntiVirus (ClamAV) versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an authenticated, local attacker to crash ClamAV at database load time, and possibly gain code execution. The vulnerability is due to improper bounds checking that may result in a multi-byte heap buffer overwflow write. An attacker could exploit this vulnerability by placing a crafted CDB ClamAV signature database file in the ClamAV database directory. An exploit could allow the attacker to run code as the clamav user.
