Subject: Security ERRATA Moderate: quagga on SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Thursday 13th September 2012 21:53:14 UTC (over 4 years ago)
Synopsis:          Moderate: quagga security update
Issue Date:        2012-09-12
CVE Numbers:       CVE-2011-3323
                    CVE-2011-3324
                    CVE-2011-3325
                    CVE-2011-3326
                    CVE-2011-3327
                    CVE-2012-0249
                    CVE-2012-0250
                    CVE-2012-0255
                    CVE-2012-1820



A heap-based buffer overflow flaw was found in the way the bgpd daemon
processed malformed Extended Communities path attributes. An attacker could
send a specially-crafted BGP message, causing bgpd on a target system to
crash or, possibly, execute arbitrary code with the privileges of the user
running bgpd. The UPDATE message would have to arrive from an explicitly
configured BGP peer, but could have originated elsewhere in the BGP
network. (CVE-2011-3327)

A stack-based buffer overflow flaw was found in the way the ospf6d daemon
processed malformed Link State Update packets. An OSPF router could use
this flaw to crash ospf6d on an adjacent router. (CVE-2011-3323)

A flaw was found in the way the ospf6d daemon processed malformed link
state advertisements. An OSPF neighbor could use this flaw to crash
ospf6d on a target system. (CVE-2011-3324)

A flaw was found in the way the ospfd daemon processed malformed Hello
packets. An OSPF neighbor could use this flaw to crash ospfd on a
target system. (CVE-2011-3325)

A flaw was found in the way the ospfd daemon processed malformed link state
advertisements. An OSPF router in the autonomous system could use this flaw
to crash ospfd on a target system. (CVE-2011-3326)

An assertion failure was found in the way the ospfd daemon processed
certain Link State Update packets. An OSPF router could use this flaw to
cause ospfd on an adjacent router to abort. (CVE-2012-0249)

A buffer overflow flaw was found in the way the ospfd daemon processed
certain Link State Update packets. An OSPF router could use this flaw to
crash ospfd on an adjacent router. (CVE-2012-0250)

Two flaws were found in the way the bgpd daemon processed certain BGP OPEN
messages. A configured BGP peer could cause bgpd on a target system to
abort via a specially-crafted BGP OPEN message. (CVE-2012-0255,
CVE-2012-1820)

We would like to thank CERT-FI for reporting CVE-2011-3327,
CVE-2011-3323, CVE-2011-3324, CVE-2011-3325, and CVE-2011-3326; and the
CERT/CC for reporting CVE-2012-0249, CVE-2012-0250, CVE-2012-0255, and
CVE-2012-1820. CERT-FI acknowledges Riku Hietamki, Tuomo Untinen and Jukka
Taimisto of the Codenomicon CROSS project as the original reporters of
CVE-2011-3327, CVE-2011-3323, CVE-2011-3324, CVE-2011-3325, and
CVE-2011-3326. The CERT/CC acknowledges Martin Winter at
OpenSourceRouting.org as the original reporter of CVE-2012-0249,
CVE-2012-0250, and CVE-2012-0255, and Denis Ovsienko as the original
reporter of CVE-2012-1820.

After installing the updated packages, the bgpd, ospfd, and ospf6d daemons
will be restarted automatically.
