Alpine: multiple netatalk packages: security update to 3.1.13-r0

critical Tenable Cloud Security Plugin ID 427024

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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 ad_addcomment 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 stack-based buffer. An attacker can leverage this
vulnerability to execute code in the context of root. Was ZDI-CAN-15876. (CVE-2022-0194)

- 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 setfilparams 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 stack-based buffer. An attacker can leverage this
vulnerability to execute code in the context of root. Was ZDI-CAN-15837. (CVE-2022-23122)
