- ------------------------------------------------------------------------Package        : link-grammar
Vulnerability  : buffer overflow
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2007-5395
Debian Bug     : 450695

Alin Rad Pop discovered that link-grammar, Carnegie Mellon University's
link grammar parser for English, performed insufficient validation within
its tokenizer, which could allow a malicious input file to execute
arbitrary code.

For the stable distribution (etch), this problem has been fixed in version
4.2.2-4etch1.

For the old stable distribution (sarge), this package was not present.

For the unstable distribution (sid), this problem was fixed in version
4.2.5-1.

We recommend that you upgrade your link-grammar package.
