Alpine: multiple clamav packages, multiple freshclam packages: security update to 0.99.3-r0

critical Tenable Cloud Security Plugin ID 403852

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- 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)
