clamav vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.10

Summary:

Several security issues were fixed in ClamAV.

Software Description:
- clamav: Anti-virus utility for Unix

Details:

It was discovered that ClamAV incorrectly handled parsing certain OLE2
files. A remote attacker could possibly use this issue to cause ClamAV to
crash, resulting in a denial of service. (CVE-2024-20290)

Amit Schendel discovered that the ClamAV ClamD service incorrectly handled
the VirusEvent feature. An attacker able to connect to ClamD could possibly
use this issue to execute arbitrary code. (CVE-2024-20328)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.10:
   clamav                          1.0.5+dfsg-0ubuntu0.23.10.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
