Bug 408507 – <net-misc/quagga-0.99.21: Multiple Vulnerabilities (CVE-2012-{0249,0250,0255,1820})

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Agostino Sarubbo 2012-03-16 15:58:49 UTC]

From secunia security advisory at $URL:

Description:
1) Two errors exist within ospfd. No further information is currently available.

2) An error within the "bgp_open_receive()" function (bgpd/bgp_packet.c) when parsing a peer input stream can be exploited to trigger an assertion and cause a crash.

The vulnerabilities are reported in versions prior to 0.99.20.1.


Solution:
Update to version 0.99.20.1.

CVE-2012-0255 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0255):
  The BGP implementation in bgpd in Quagga before 0.99.20.1 does not properly
  use message buffers for OPEN messages, which allows remote attackers to
  cause a denial of service (assertion failure and daemon exit) via a message
  associated with a malformed Four-octet AS Number Capability (aka AS4
  capability).

CVE-2012-0250 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0250):
  Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before
  0.99.20.1 allows remote attackers to cause a denial of service (daemon
  crash) via a Link State Update (aka LS Update) packet containing a
  network-LSA link-state advertisement for which the data-structure length is
  smaller than the value in the Length header field.

CVE-2012-0249 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0249):
  Buffer overflow in the ospf_ls_upd_list_lsa function in ospf_packet.c in the
  OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote
  attackers to cause a denial of service (assertion failure and daemon exit)
  via a Link State Update (aka LS Update) packet that is smaller than the
  length specified in its header.

CVE-2012-1820 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1820):
  The bgp_capability_orf function in bgpd in Quagga 0.99.20.1 and earlier
  allows remote attackers to cause a denial of service (assertion failure and
  daemon exit) by leveraging a BGP peering relationship and sending a
  malformed Outbound Route Filtering (ORF) capability TLV in an OPEN message.

0.99.21 is in tree now.

Arches, please test and mark stable =net-misc/quagga-0.99.21

Please get rid of USE=logrotate (see bug #198901).

(In reply to comment #4)
> Please get rid of USE=logrotate (see bug #198901).

Fixed that.

Stable for HPPA.

[Comment 7 Agostino Sarubbo 2012-12-07 10:25:05 UTC]

since there are at least 2 compile failures, I'm wondering on how hppa has tested it.
