The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14692-1 advisory.

  - A vulnerability in the Excel XLM macro parsing module in Clam AntiVirus (ClamAV) Software versions 0.103.0     and 0.103.1 could allow an unauthenticated, remote attacker to cause a denial of service condition on an     affected device. The vulnerability is due to improper error handling that may result in an infinite loop.
    An attacker could exploit this vulnerability by sending a crafted Excel file to an affected device. An     exploit could allow the attacker to cause the ClamAV scanning process hang, resulting in a denial of     service condition. (CVE-2021-1252)

  - A vulnerability in the PDF parsing module in Clam AntiVirus (ClamAV) Software versions 0.103.0 and 0.103.1     could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected     device. The vulnerability is due to improper buffer size tracking that may result in a heap buffer over-     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 to crash, resulting in a denial of     service condition. (CVE-2021-1404)

  - A vulnerability in the email parsing module in Clam AntiVirus (ClamAV) Software version 0.103.1 and all     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 variable initialization that may result in an     NULL pointer read. An attacker could exploit this vulnerability by sending a crafted email to an affected     device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a     denial of service condition. (CVE-2021-1405)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
