Three SCO Security Advisories:
1. SCOSA-2005.9 - OpenServer 5.0.6 OpenServer 5.0.7 :
Vulnerabilities in long-lived TCP connections / Rose attack

Detail
======
1. TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.
2. TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.
3. Racoon is the daemon which negotiates and configures a set of parameters of IPsec. Several security issues are addressed with this patch.

SCO Security Advisory
Subject: UnixWare 7.1.4 : racoon multilple security issues
Advisory number: SCOSA-2005.10
Issue date: 2005 February 07
Cross reference: sr890909 fz529836 erg712650 CAN-2004-0155 CAN-2004-0164
CAN-2004-0392 CAN-2004-0403 CAN-2004-0607 ______________________________________________________________________________
1. Problem Description
Racoon is the daemon which negotiates and configures a set
of parameters of IPsec. Several security issues are addressed
with this patch.
The KAME IKE Daemon Racoon, when authenticating a peer during
Phase 1, validates the X.509 certificate but does not verify
the RSA signature authentication, which allows remote attackers
to establish unauthorized IP connections or conduct
man-in-the-middle attacks using a valid, trusted X.509
certificate.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0155 to this issue.
KAME IKE daemon (racoon) does not properly handle hash values,
which allows remote attackers to delete certificates via a
certain delete message that is not properly handled in isakmp.c
or isakmp_inf.c, or a certain INITIAL-CONTACT message that
is not properly handled in isakmp_inf.c.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned th e name CAN-2004-0164 to this issue.
racoon before 20040407b allows remote attackers to cause a denial
of service (infinite loop and dropped connections) via an IKE
message with a malformed Generic Payload Header containing
invalid "Security Association Next Payload" and "RESERVED" fields.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned th e name CAN-2004-0392 to this issue.
Racoon before 20040408a allows remote attackers to cause a denial
of service (memory consumption) via an ISAKMP packet with a large
length field.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned th e name CAN-2004-0403 to this issue.
The eay_check_x509cert function in KAME Racoon successfully
verifies certificates even when OpenSSL validation fails,
which could allow remote attackers to bypass authentication.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0607 to this issue.
