NETATALK GITHUB CODE

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Netatalk. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. 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. The specific flaw exists within the getdirparams method. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Netatalk. The specific flaw exists within the get_finderinfo method. An attacker can leverage this vulnerability to execute code in the context of root. 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. The specific flaw exists within the copyapplfile 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. The specific flaw exists within the dsi_writeinit function. This provides remote root access on some platforms such as FreeBSD (used for TrueNAS). Netatalk through 3.1.13 has an afp_getappl heap-based buffer overflow resulting in code execution via a crafted.
