On April 20, 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 the TIFF file parser of Clam AntiVirus (ClamAV) versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional information becomes available.

The remote host is affected by the vulnerability described in GLSA-202310-01 (ClamAV: Multiple Vulnerabilities)

  - A vulnerability in the OOXML parsing module in Clam AntiVirus (ClamAV) Software version 0.104.1 and LTS     version 0.103.4 and prior versions could allow an unauthenticated, remote attacker to cause a denial of     service condition on an affected device. The vulnerability is due to improper checks that may result in an     invalid pointer read. An attacker could exploit this vulnerability by sending a crafted OOXML file to an     affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash,     resulting in a denial of service condition. (CVE-2022-20698)

  - On April 20, 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 CHM file parser of Clam AntiVirus (ClamAV)     versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an     unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a     description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional     information becomes available. (CVE-2022-20770)

  - On April 20, 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 the TIFF file parser of Clam AntiVirus (ClamAV)     versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an     unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a     description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional     information becomes available. (CVE-2022-20771)

  - On April 20, 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 HTML file parser of Clam AntiVirus (ClamAV)     versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an     unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a     description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional     information becomes available. (CVE-2022-20785)

  - 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.
    (CVE-2022-20792)

  - 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-2022-20796)

  - 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-2022-20803)

  - 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-2023-20032)

  - 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-2023-20052)

  - On April 20, 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 CHM file parser of Clam AntiVirus (ClamAV)     versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an     unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a     description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional     information becomes available. (CVE-2022-20770)

  - On April 20, 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 HTML file parser of Clam AntiVirus (ClamAV)     versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior versions could allow an     unauthenticated, remote attacker to cause a denial of service condition on an affected device. For a     description of this vulnerability, see the ClamAV blog. This advisory will be updated as additional     information becomes available. (CVE-2022-20785)

  - 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.
