Synopsis

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

Description

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1184-1 advisory.

- This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Synology DiskStation Manager. Authentication is not required to exploit this vulnerablity. The specific flaw exists within the processing of DSI structures in Netatalk. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12326.
(CVE-2021-31439)

- 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 parse_entries function. The issue results from the lack of proper error handling when parsing AppleDouble entries. An attacker can leverage this vulnerability to execute code in the context of root.
Was ZDI-CAN-15819. (CVE-2022-23121)

- 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 copyapplfile function. When parsing the len element, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15869. (CVE-2022-23125)

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 libatalk12, netatalk and / or netatalk-devel packages.
