Ubuntu 23.10 : ClamAV vulnerabilities (USN-6636-1)

high Nessus Plugin ID 190581

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6636-1 advisory.

 - A vulnerability in the OLE2 file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an incorrect check for end-of-string values during scanning, which may result in a heap buffer over-read. An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software and consuming available system resources. For a description of this vulnerability, see the ClamAV blog .
 (CVE-2024-20290)

 - The vulnerability exists due to improper input validation in the VirusEvent feature. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system. (CVE-2024-20328)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
