What is CVE-2013-10042?
A stack-based buffer overflow vulnerability has been identified in freeFTPd versions up to 1.0.10, particularly in the processing of the FTP PASS command. This flaw arises from insufficient validation of input length for password strings provided by users. An attacker can exploit this vulnerability by sending a specially crafted password, which can lead to memory corruption. If succeeded, it may cause denial of service or allow execution of arbitrary code. It's important to note that exploitation requires the anonymous user account to be activated, making it critical for users to review their configuration and security practices.
