Broken cipher list retrieval in plugins 26928, 31705
|
|
Plugins ssl_anon_ciphers.nasl and ssl_weak_supported_ciphers.nasl
obtain the list of supported SSL ciphers via get_kb_list(). Both of
these plugins are currently broken because they do not flatten the
cipher hash before testing for its emptiness with max_index(). This
causes the plugins to terminate early due to perceived lack of data.
The following patch resolves the issue:
--- ssl_anon_ciphers.nasl.orig 2008-03-28 10:16:44.000000000 -0400
+++ ssl_anon_ciphers.nasl 2008-12-30 12:50:56.000000000 -0500
