CVE-2015-3674

Vulnerability

The afpserver daemon in Apple OS X versions prior to 10.10.4 contains a memory corruption vulnerability that can be triggered via unspecified vectors. The issue resides in the handling of network requests, allowing an attacker to corrupt memory and potentially execute arbitrary code. The exact code path and required conditions are not disclosed in the available reference [1].

Exploitation

A remote attacker can exploit this vulnerability by sending specially crafted network traffic to the afpserver service. No authentication is required, and the attack can be launched over the network without user interaction. The specific sequence of steps is not detailed in the advisory [1].

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the afpserver process, or cause a denial of service through memory corruption. This could lead to full system compromise or disruption of file sharing services [1].

Mitigation

Apple addressed this vulnerability in OS X Yosemite 10.10.4 and Security Update 2015-005, released on July 1, 2015. Users should upgrade to the latest version of OS X to mitigate the risk. No workarounds are provided in the advisory [1].
