Synopsis

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

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-aaeb45fb73 advisory.

 - This vulnerability allows remote attackers to execute arbitrary code on affected installations of Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dsi_writeinit function. The issue results from the lack of proper validation of the length of user- supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-17646. (CVE-2022-43634)

 - Netatalk through 3.1.13 has an afp_getappl heap-based buffer overflow resulting in code execution via a crafted .appl file. This provides remote root access on some platforms such as FreeBSD (used for TrueNAS).
 (CVE-2022-45188)

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 5:netatalk package.
