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 NULL pointer dereference flaw was found in the way the bgpd daemon processed malformed route Extended Communities attributes. A configured BGP peer could crash bgpd on a target system via a specially crafted BGP message. (CVE-2010-1674)
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)
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 and CVE-2012-0250.
