The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-3439911df6 advisory.
A vulnerability in the VirusEvent feature of ClamAV could allow a local attacker to inject arbitrary commands with the privileges of the application service account.The vulnerability is due to unsafe handling of file names. A local attacker could exploit this vulnerability by supplying a file name containing command-line sequences. When processed on a system using configuration options for the VirusEvent feature, the attacker could cause the application to execute arbitrary commands. ClamAV has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. (CVE-2024-20328)
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)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
