Description

The ClamAV AntiVirus software versions 0.99.2 and prior contain a
vulnerability that could allow an unauthenticated, remote attacker to
cause a denial of service (DoS) condition on an affected device. The
vulnerability is due to a lack of input validation checking mechanisms
during certain mail parsing operations (mbox.c operations on bounce
messages). If successfully exploited, the ClamAV software could allow a
variable pointing to the mail body which could cause a used after being
free (use-after-free) instance which may lead to a disruption of services
on an affected device to include a denial of service condition.
(CVE-2017-12374)

The ClamAV AntiVirus software versions 0.99.2 and prior contain a
vulnerability that could allow an unauthenticated, remote attacker to
cause a denial of service (DoS) condition on an affected device. The
vulnerability is due to a lack of input validation checking mechanisms
during certain mail parsing functions (the rfc2047 function in mbox.c). An
unauthenticated, remote attacker could exploit this vulnerability by
sending a crafted email to the affected device. This action could cause a
buffer overflow condition when ClamAV scans the malicious email, allowing
the attacker to potentially cause a DoS condition on an affected device.
(CVE-2017-12375)

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability
that could allow an unauthenticated, remote attacker to cause a denial of
service (DoS) condition or potentially execute arbitrary code on an affected
device. The vulnerability is due to improper input validation checking
mechanisms when handling Portable Document Format (.pdf) files sent to an
affected device. An unauthenticated, remote attacker could exploit this
vulnerability by sending a crafted .pdf file to an affected device. This
action could cause a handle_pdfname (in pdf.c) buffer overflow when ClamAV
scans the malicious file, allowing the attacker to cause a DoS condition
or potentially execute arbitrary code. (CVE-2017-12376)

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability
that could allow an unauthenticated, remote attacker to cause a denial of
service (DoS) condition or potentially execute arbitrary code on an affected
device. The vulnerability is due to improper input validation checking
mechanisms in mew packet files sent to an affected device. A successful
exploit could cause a heap-based buffer over-read condition in mew.c when
ClamAV scans the malicious file, allowing the attacker to cause a DoS
condition or potentially execute arbitrary code on the affected device.
(CVE-2017-12377)

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability
that could allow an unauthenticated, remote attacker to cause a denial of
service (DoS) condition on an affected device. The vulnerability is due to
improper input validation checking mechanisms of .tar (Tape Archive) files
sent to an affected device. A successful exploit could cause a checksum
buffer over-read condition when ClamAV scans the malicious .tar file,
potentially allowing the attacker to cause a DoS condition on the affected
device. (CVE-2017-12378)

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability
that could allow an unauthenticated, remote attacker to cause a denial of
service (DoS) condition or potentially execute arbitrary code on an affected
device. The vulnerability is due to improper input validation checking
mechanisms in the message parsing function on an affected system. An
unauthenticated, remote attacker could exploit this vulnerability by sending
a crafted email to the affected device. This action could cause a
messageAddArgument (in message.c) buffer overflow condition when ClamAV
scans the malicious email, allowing the attacker to potentially cause a DoS
condition or execute arbitrary code on an affected device. (CVE-2017-12379)

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability
that could allow an unauthenticated, remote attacker to cause a denial of
service (DoS) condition on an affected device. The vulnerability is due to
improper input validation checking mechanisms in mbox.c during certain mail
parsing functions of the ClamAV software. An unauthenticated, remote
attacker could exploit this vulnerability by sending a crafted email to the
affected device. An exploit could trigger a NULL pointer dereference
condition when ClamAV scans the malicious email, which may result in a DoS
condition. (CVE-2017-12380)
