Alpine: multiple clamav packages, multiple freshclam packages: security update to 1.0.1-r0

critical Tenable Cloud Security Plugin ID 403854

Description

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

 - On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability
 in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7
 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code. This vulnerability
 is due to a missing buffer size check that may result in a heap buffer overflow write. An attacker could
 exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an
 affected device. A successful exploit could allow the attacker to execute arbitrary code with the
 privileges of the ClamAV scanning process, or else crash the process, resulting in a denial of service
 (DoS) condition. For a description of this vulnerability, see the ClamAV blog
 ["https://blog.clamav.net/"]. (CVE-2023-20032)

 - On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability
 in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier
 could allow an unauthenticated, remote attacker to access sensitive information on an affected device.
 This vulnerability is due to enabling XML entity substitution that may result in XML external entity
 injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by
 ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file
 that may be read by the ClamAV scanning process. (CVE-2023-20052)
