Description Kurt Seifried 2012-12-15 12:12:13 UTC

Matthias Weckbecker (mweckbecker) reported on OSS-SEC that the thttpd
daemon may experience a denial of service when using glibc due to glibc 
crypt()returning a NULL while dereferencing. This can be triggered via a 
specially formatted .htpassword entry that is then used to authenticate for 
example.
