An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes.

Other sources

Squid could allow a remote attacker to obtain sensitive information, caused by incorrect data management when translating FTP server listings into HTTP responses. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain user sessions or non-Squid processes information, and use this information to launch further attacks against the affected system.
