Alpine: multiple clamav packages, multiple freshclam packages: security update to 1.3.2-r0

medium Tenable Cloud Security Plugin ID 426145

Description

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

 - A vulnerability in the PDF parsing module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior
 versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and
 0.103.11 and all prior versions could allow an unauthenticated, remote attacker to cause a denial of
 service (DoS) condition on an affected device. The vulnerability is due to an out of bounds read. An
 attacker could exploit this vulnerability by submitting a crafted PDF file to be scanned by ClamAV on an
 affected device. An exploit could allow the attacker to terminate the scanning process. (CVE-2024-20505)

 - A vulnerability in the ClamD service module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior
 versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and
 0.103.11 and all prior versions could allow an authenticated, local attacker to corrupt critical system
 files. The vulnerability is due to allowing the ClamD process to write to its log file while privileged
 without checking if the logfile has been replaced with a symbolic link. An attacker could exploit this
 vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a
 way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by
 appending ClamD log messages after restart. (CVE-2024-20506)
