The rsvp_print function in tcpdump 3.9.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via a crafted RSVP packet of length 4. A buffer overflow in certain Apple AirPort drivers may allow an attacker to execute arbitrary code with system privileges, or create a denial-of-service condition. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. ------------ This vulnerability information is a summary of multiple vulnerabilities released at the same time. Please note that the contents of vulnerability information other than the title are included. ------------ tcpdump Is a management tool for capturing network traffic and supports multiple protocols. The issue occurs because of the way tcpdump decodes Resource ReSerVation Protocol (RSVP) packets. This issue affects tcpdump 3.9.x/CVS and earlier. This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig72CF56A4065A77499C855538 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable --------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated tcpdump packages fix security issues Advisory ID: FLSA:156139 Issue date: 2006-04-04 Product: Red Hat Linux, Fedora Core Keywords: Bugfix, Security CVE Names: CVE-2005-1267, CVE-2005-1278, CVE-2005-1279, CVE-2005-1280 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: Updated tcpdump packages that fix several security issues are now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 Fedora Core 1 - i386 Fedora Core 2 - i386 3. Problem description: Several denial of service bugs were found in the way tcpdump processes certain network packets. It is possible for an attacker to inject a carefully crafted packet onto the network, crashing a running tcpdump session. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-1267, CVE-2005-1278, CVE-2005-1279, and CVE-2005-1280 to these issues. Users of tcpdump are advised to upgrade to these erratum packages, which contain backported security patches and are not vulnerable to these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. Certain TCP implementations may allow a remote attacker to arbitrarily modify host timestamp values, leading to a denial-of-service condition. TCP The implementation of the time stamp option is TCP A vulnerability exists that allows the internal timer on a connection to be changed to any value.the system TCP Connection reset and service disruption (DoS) It may be in a state. The Transmission Control Protocol (TCP) defined in RFC 793 allows reliable host-to-host transmission in a message exchange network. RFC 1323 introduces a number of technologies that enhance TCP performance, two of which are TCP timestamps and sequence number rollback protection (PAWS).  There are security holes in the PAWS technology of TCP RFC 1323. If TCP timestamps are enabled, both endpoints of the TCP connection use the internal clock to mark the TCP header with the timestamp value.  This vulnerability can occur if an attacker sends enough TCP PAWS packets to the vulnerable computer. An attacker can set the message timestamp to a large value. When the target machine processes this message, the internal timer will be updated to this value, which may cause all valid messages received afterwards to be discarded because these messages are considered too old or invalid. This technique may cause the target connection to deny service. ---------------------------------------------------------------------- Bist Du interessiert an einem neuen Job in IT-Sicherheit?

Cisco has acknowledged that various Cisco products are affected. The published Internet-Draft details three types of attacks, which utilize the following ICMP messages to cause a negative impact on TCP connections either terminating or originating from a vulnerable device. 1) ICMP "hard" error messages 2) ICMP "fragmentation needed and Don't Fragment (DF) bit set" messages (known as PMTUD attacks) 3) ICMP "source quench" messages These attacks can all be exploited to cause TCP connection resets, reduce the throughput in existing TCP connections, or consume large amounts of CPU and memory resources. NOTE: See the original advisory for a list of affected versions. SOLUTION: See patch matrix in vendor advisory for information about fixes
