"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2022:0493-1 advisory.
- 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)
