TITLE:
WordNet Multiple Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA30242

VERIFY ADVISORY:
http://secunia.com/advisories/30242/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
WordNet 3.x
http://secunia.com/product/18659/

DESCRIPTION:
Some vulnerabilities have been reported in WordNet, which potentially
can be exploited by malicious people to compromise a vulnerable
system.

The vulnerabilities are caused due to boundary errors within the
"searchwn()" function in src/wn.c and within the "wngrep()" function
in lib/search.c. These can be exploited to cause stack-based buffer
overflows via overly long strings passed as arguments to the "wn"
binary.

Successful exploitation may allow execution of arbitrary code, but
requires that the application is accessible e.g. via a web server.

The vulnerabilities are reported in version 3.0. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Reported in a Gentoo bug report by Jukka Ruohonen.
