DSA-3251 dnsmasq – security update

Nick Sampanis discovered that dnsmasq, a small caching DNS proxy and
DHCP/TFTP server, did not properly check the return value of the
setup_reply() function called during a TCP connection, which is used
then as a size argument in a function which writes data on the client’s
connection. A remote attacker could exploit this issue via a specially
crafted DNS request to cause dnsmasq to crash, or potentially to obtain
sensitive information from process memory.

MDVSA-2015:226: fcgi

Updated fcgi packages fix security vulnerability:

FCGI does not perform range checks for file descriptors before use of
the FD_SET macro. This FD_SET macro could allow for more than 1024
total file descriptors to be monitored in the closing state. This
may allow remote attackers to cause a denial of service (stack memory
corruption, and infinite loop or daemon crash) by opening many socket
connections to the host and crashing the service (CVE-2012-6687).

MDVSA-2015:225: cherokee

Updated cherokee packages fix security vulnerability:

The cherokee_validator_ldap_check function in validator_ldap.c in
Cherokee 1.2.103 and earlier, when LDAP is used, does not properly
consider unauthenticated-bind semantics, which allows remote attackers
to bypass authentication via an empty password (CVE-2014-4668).

MDVSA-2015:224: ruby

Updated ruby packages fix security vulnerability:

Ruby OpenSSL hostname matching implementation violates RFC 6125
(CVE-2015-1855).

The ruby packages for MBS2 has been updated to version 2.0.0-p645,
which fixes this issue.

MDVSA-2015:223: directfb

Updated directfb packages fix security vulnerabilities:

Multiple integer signedness errors in the Dispatch_Write function
in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB allow
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code via the Voodoo interface, which triggers a
stack-based buffer overflow (CVE-2014-2977).

The Dispatch_Write function in
proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB allows
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code via the Voodoo interface, which triggers an
out-of-bounds write (CVE-2014-2978).
