## Description

A vulnerability in the Portable Executable (PE) file scanning functionality
of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow
an unauthenticated, remote attacker to cause a denial of service condition
on an affected device. The vulnerability is due to a lack of proper input
and validation checking mechanisms for PE files sent an affected device. An
attacker could exploit this vulnerability by sending malformed PE files to
the device running an affected version ClamAV Software. An exploit could
allow the attacker to cause an out-of-bounds read condition, resulting in a
crash that could result in a denial of service condition on an affected
device.
