Description From 2010-11-01 16:08:54
Two vulnerabilities have been reported in ProFTPD, which can be exploited by
malicious users to manipulate certain data and malicious people to compromise a
vulnerable system.

1) A logic error within the "pr_netio_telnet_gets()" function in src/netio.c
when processing user input containing the Telnet IAC (Interpret As Command)
escape sequence can be exploited to cause a stack-based buffer overflow by
sending specially crafted input to the FTP or FTPS service.

Successful exploitation may allow execution of arbitrary code.

2) An input validation error within the "mod_site_misc" module can be exploited
to e.g. create and delete directories, create symlinks, and change the time of
files located outside a writable directory.

Successful exploitation requires that ProFTPD is compiled with the
"mod_site_misc" module and the attacker has write access to a directory.

Fixed in 1.3.3c
