Debian DLA-3426-1 : netatalk - LTS security update

critical Nessus Plugin ID 175966

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3426 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 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)

- This vulnerability allows remote attackers to disclose sensitive information on affected installations of Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getdirparams method. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-15830.
(CVE-2022-23123)

- This vulnerability allows remote attackers to disclose sensitive information on affected installations of Netatalk. Authentication is not required to exploit this vulnerability. The specific flaw exists within the get_finderinfo method. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI- CAN-15870. (CVE-2022-23124)

- 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)

- 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

Upgrade the netatalk packages.

For Debian 10 buster, these problems have been fixed in version 3.1.12~ds-3+deb10u1.
