CVE-2011-4128: Buffer Overflow
First published: Wed Nov 09 2011(Updated: )
A flaw was reported [1] in the GnuTLS gnutls_session_get_data() function, which could overflow a too-short buffer parameter allocated by the caller. The test which was to avoid such buffer overflows was not working. A malicious server could use this flaw in a vulnerable client to send a larger SessionTicket in the hope of overflowing the client. Upstream has indicated that they are unaware of any client software that does not properly use the session resumption functions; clients that perform session resumption as documented [2] are not vulnerable.
