Scientific Linux Security Update : quagga on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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

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.
