| Description: | Summary:
The remote host is missing an update for the 'openssl' package(s) announced via the SSA:2014-288-01 advisory.
Vulnerability Insight:
New openssl packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1,
and -current to fix security issues.
Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/openssl-solibs-1.0.1j-i486-1_slack14.1.txz: Upgraded.
(* Security fix *)
patches/packages/openssl-1.0.1j-i486-1_slack14.1.txz: Upgraded.
This update fixes several security issues:
SRTP Memory Leak (CVE-2014-3513):
A flaw in the DTLS SRTP extension parsing code allows an attacker, who
sends a carefully crafted handshake message, to cause OpenSSL to fail
to free up to 64k of memory causing a memory leak. This could be
exploited in a Denial Of Service attack.
Session Ticket Memory Leak (CVE-2014-3567):
When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
integrity of that ticket is first verified. In the event of a session
ticket integrity check failing, OpenSSL will fail to free memory
causing a memory leak. By sending a large number of invalid session
tickets an attacker could exploit this issue in a Denial Of Service
attack.
SSL 3.0 Fallback protection:
OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications
to block the ability for a MITM attacker to force a protocol
downgrade.
Some client applications (such as browsers) will reconnect using a
downgraded protocol to work around interoperability bugs in older
servers. This could be exploited by an active man-in-the-middle to
downgrade connections to SSL 3.0 even if both sides of the connection
support higher protocols. SSL 3.0 contains a number of weaknesses
including POODLE (CVE-2014-3566).
Build option no-ssl3 is incomplete (CVE-2014-3568):
When OpenSSL is configured with 'no-ssl3' as a build option, servers
could accept and complete a SSL 3.0 handshake, and clients could be
configured to send them.
