Debian: wget directory traversal buffer overflow
Summary
Package : wget
Problem type : directory traversal
buffer overflow
Debian-specific: no
CVEs : CAN-2002-1344
Two problems have been found in the wget package as distributed in
Debian GNU/Linux:
* Stefano Zacchiroli found a buffer overrun in the url_filename function,
which would make wget segfault on very long URLs
* Steven M. Christey discovered that wget did not verify the FTP server
response to a NLST command: it must not contain any directory information,
since that can be used to make a FTP client overwrite arbitrary files.
Both problems have been fixed in version 1.5.3-3.1 for Debian GNU/Linux
2.2/potato and version 1.8.1-6.1 for Debian GNU/Linux 3.0/woody.
