ID CVE-2017-5495
Summary All versions of Quagga, 0.93 through 1.1.0, are vulnerable to an unbounded memory allocation in the telnet 'vty' CLI, leading to a Denial-of-Service of Quagga daemons, or even the entire host. When Quagga daemons are configured with their telnet CLI enabled, anyone who can connect to the TCP ports can trigger this vulnerability, prior to authentication. Most distributions restrict the Quagga telnet interface to local access only by default. The Quagga telnet interface 'vty' input buffer grows automatically, without bound, so long as a newline is not entered. This allows an attacker to cause the Quagga daemon to allocate unbounded memory by sending very long strings without a newline. Eventually the daemon is terminated by the system, or the system itself runs out of memory. This is fixed in Quagga 1.1.1 and Free Range Routing (FRR) Protocol Suite 2017-01-10.

CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

[CVE-2017-16227, bsc#1065641] - The Quagga BGP daemon did not check whether data sent to peers via NOTIFY had an invalid attribute length. It was possible to exploit this issue and cause the bgpd process to leak sensitive information over the network to a configured peer. [CVE-2018-5378, bsc#1079798] - The Quagga BGP daemon used to double-free memory when processing certain forms of UPDATE messages. This issue could be exploited by sending an optional/transitive UPDATE attribute that all conforming eBGP speakers should pass along. Consequently, a single UPDATE message could have affected many bgpd processes across a wide area of a network. Through this vulnerability, attackers could potentially have taken over control of affected bgpd processes remotely. [CVE-2018-5379, bsc#1079799] - It was possible to overrun internal BGP code-to-string conversion tables in the Quagga BGP daemon. Configured peers could have exploited this issue and cause bgpd to emit debug and warning messages into the logs that would contained arbitrary bytes. [CVE-2018-5380, bsc#1079800] - The Quagga BGP daemon could have entered an infinite loop if sent an invalid OPEN message by a configured peer. If this issue was exploited, then bgpd would cease to respond to any other events. BGP sessions would have been dropped and not be reestablished. The CLI interface would have been unresponsive. The bgpd daemon would have stayed in this state until restarted.

    title SUSE SLES12 Security Update : quagga (SUSE-SU-2018:0455-1)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2017-2294-1.NASL
    description This update provides Quagga 1.1.1, which brings several fixes and enhancements. Security issues fixed : - CVE-2017-5495: Telnet 'vty' interface DoS due to unbounded memory allocation. (bsc#1021669) - CVE-2016-1245: Stack overrun in IPv6 RA receive code. (bsc#1005258) Bug fixes : - Do not enable zebra's TCP interface (port 2600) to use default UNIX socket for communication between the daemons. (fate#323170) Between 0.99.22.1 and 1.1.1 the following improvements have been implemented : - Changed the default of 'link-detect' state, controlling whether zebra will respond to link-state events and consider an interface to be down when link is down. To retain the current behavior save your config before updating, otherwise remove the 'link-detect' flag from your config prior to updating. There is also a new global 'default link-detect (on|off)' flag to configure the global default. - Greatly improved nexthop resolution for recursive routes. - Event driven nexthop resolution for BGP. - Route tags support. - Transport of TE related metrics over OSPF, IS-IS. - IPv6 Multipath for zebra and BGP. - Multicast RIB support has been extended. It still is IPv4 only. - RIP for IPv4 now supports equal-cost multipath (ECMP). - route-maps have a new action 'set ipv6 next-hop peer-address'. - route-maps have a new action 'set as-path prepend last-as'. - 'next-hop-self all' to override nexthop on iBGP route reflector setups. - New pimd daemon provides IPv4 PIM-SSM multicast routing. - IPv6 address management has been improved regarding tentative addresses. This is visible in that a freshly configured address will not immediately be marked as usable. - Recursive route support has been overhauled. Scripts parsing 'show ip route' output may need adaptation. - A large amount of changes has been merged for ospf6d. Careful evaluation prior to deployment is recommended. - Multiprotocol peerings over IPv6 now try to find a more appropriate IPv4 nexthop by looking at the interface. - Relaxed bestpath criteria for multipath and improved display of multipath routes in 'show ip bgp'. Scripts parsing this output may need to be updated. - Support for iBGP TTL security. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
