Technical details
An out-of-bounds write vulnerability (CWE-787) exists in the convert_charset() function of Netatalk versions 2.0.4 through 4.4.2. The flaw occurs during null termination when the converted output exactly fills the caller-supplied destination buffer, causing the function to write two null bytes past the buffer boundary. An authenticated attacker can exploit this over the network to trigger memory corruption, potentially leading to a denial-of-service (process crash) or arbitrary code execution. The attack complexity is considered high as it requires specific conditions during charset conversion. The issue is resolved in Netatalk version 4.4.3.
