This isn't an attempt at an exploit, its more like a public service announcement letting you know about a vulnerability so you can upgrade.
I believe the stuff around the text is a PGP signature, but I could be wrong.
Looks like hex obfuscation of malicious code.
I could be wrong though, it could just be a warning.
http://www.technicalinfo.net/papers/CSS.htmlThe hex value of a character may be used, often done for non-printable characters. Such as:
x00 Null bytes for truncating strings
x04 EOF for faking the end of files
x08 Backspace x0a New Line for extra command execution
x0d New Line for extra command execution
x1b Escape character for breaking out of procedures
x20 Spaces for faking URLs and other names
x7f Delete
