Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-331-1)
Summary:	The remote host is missing an update for the Debian 'polarssl' package(s) announced via the DLA-331-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'polarssl' package(s) announced via the DLA-331-1 advisory. Vulnerability Insight: A flaw was found in PolarSSl and mbed TLS: When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension and the server name indication (SNI) extension. Although most of the vulnerable code is not present in the Squeeze version, this upload contains at least a length check for incoming data. Affected Software/OS: 'polarssl' package(s) on Debian 6. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
