Security researchers Marsh Ray and Steve Dispensa unveiled the TLS (Transport Layer Security) flaw on Wednesday, following the disclosure of separate, but similar, security findings. TLS and its predecessor, SSL (Secure Sockets Layer), are typically used by online retailers and banks to provide security for web transactions. Ray explained in a blog post on Thursday that he had initially discovered the flaw in August, and demonstrated a working exploit to Dispensa at the beginning of September. This vulnerability could impact any Cisco product that uses any version of TLS and SSL.

Slow ADSL with 12.4 IOS version?!

Recently, I have upgraded my Cisco 2650XM from 12.3 to 12.4 version; I use it to connect my PC to Internet, but something goes wrong. After the upgrading, I have tried to downlad an ISO image but the speed was very low (about 300KB/s and not 700KB/s). Mhhh this is strange! I have begun the troubleshooting but no error, no warning message. So I have reset my current configuration, but nothing… no real improvement.
