CVE-2020-3327

A vulnerability in the ARJ archive parsing module in Clam AntiVirus
(ClamAV) could allow an unauthenticated, remote attacker to cause a
denial of service condition on an affected device. The vulnerability
is due to a heap buffer overflow read. An attacker could exploit this
vulnerability by sending a crafted ARJ file 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-2020-3341

A vulnerability in the PDF archive parsing module in Clam AntiVirus
(ClamAV) could allow an unauthenticated, remote attacker to cause a
denial of service condition on an affected device. The vulnerability
is due to a stack-based buffer overflow 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
crash, resulting in a denial of service condition.

For Debian 8 'Jessie', these problems have been fixed in version
0.101.5+dfsg-0+deb8u2.

We recommend that you upgrade your clamav packages.
