An issue was discovered in Listary through 6. Improper implementation of the update process leads to the download of software updates with a /check-update HTTP-based connection.

Buffer overflows in Ecartis (formerly Listar) 1.0.0 before snapshot 20020125 allows remote attackers to execute arbitrary code via (1) address_match() of mystring.c or (2) other functions in tolist.c.

Ecartis (formerly Listar) 1.0.0 in snapshot 20020125 and earlier does not properly drop privileges when Ecartis is installed setuid-root, "lock-to-user" is not set, and ecartis is called by certain MTA's, which could allow local users to gain privileges.

Buffer overflows in Ecartis (formerly Listar) 1.0.0 in snapshot 20020427 and earlier allow local users to gain privileges via (1) a long command line argument, which is not properly handled in core.c, or possibly via bad uses of sprintf() in (2) moderate.c, (3) lcgi.c, (4) fileapi.c, (5) cookie.c, (6) codes.c, or other files.
