Description Vincent Danen 2011-05-16 20:47:11 UTC

A Debian bug report [1] indicates:

"My concern is the third gnutls_record_recv() call. 'maxlen' argument
of TLS_readline() was passed to the call as is, and TLS_readline()
callers *always pass the full size* of TLS_buffer[] as 'maxlen', but
pointer passed to the gnutls_record_recv() is (TLS_buffer + some
offset). So, in theory, remote side could send specifically prepared
data which could overwrite up to MAXTOREAD bytes past the buffer. As
I'm not a security expert, I can't say for sure if it is really
exploitable or not, but it does not look good at all."

To exploit, a user would need to be coerced into running echoping against a malicious HTTPS site that sends back certain crafted data.  This affects version 6.0.2 as found in Fedora; upstream has committed a fix [2].
