-
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.

NASL family | SuSE Local Security Checks | NASL id | OPENSUSE-2017-551.NASL | description | This update for quagga to version 1.1.1 fixes the following issues :
This security issue was fixed :
- CVE-2017-5495: Quagga was 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 (bsc#1021669).
These non-security issues were fixed :
- Disabled passwords in default zebra.conf config file,
causing to disable vty telnet interface by default. The
vty interface is available via 'vtysh' utility using pam
authentication to permit management access for root
without password (boo#1021669).
- Changed owner of /etc/quagga to quagga:quagga to permit
to manage quagga via vty interface.
- Added quagga.log and create and su statemets to
logrotate config, changed default zebra log file name
from quagga.log to zebra.log.
- Added libfpm_pb0 and libquagga_pb0 shared library
sub-packages, adjusted libzebra0 sub-package name to
libzebra1.
- Do not enable zebra's tcp interface (port 2600) to use
default unix socket for communication between the
daemons
A digest of the other changes by the version upgrade :
- isisd: Fix size of malloc
- isisd: check for the existance of the correct list
- ospf6d: fix off-by-one on display of spf reasons
- ospf6d: don't access nexthops out of bounds
- bgpd: fix off-by-one in attribute flags handling
- bgpd: Fix buffer overflow error in bgp_dump_routes_func

NASL family | SuSE Local Security Checks | NASL id | SUSE_SU-2018-0455-1.NASL | description | This update for quagga fixes the following security issues :
- The Quagga BGP daemon contained a bug in the AS_PATH
size calculation that could have been exploited to
facilitate a remote denial-of-service attack via
specially crafted BGP UPDATE messages. [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. [CVE-2018-5381,
bsc#1079801]
- The Quagga daemon's telnet 'vty' CLI contains an
unbounded memory allocation bug that could be exploited
for a denial-of-service attack on the daemon. This issue
has been fixed. [CVE-2017-5495, bsc#1021669]
- The telnet 'vty' CLI of the Quagga daemon is no longer
enabled by default, because the passwords in the default
'zebra.conf' config file are now disabled. The vty
interface is available via 'vtysh' utility using pam
authentication to permit management access for root
without password. [bsc#1021669]

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.

NASL family | Huawei Local Security Checks | NASL id | EULEROS_SA-2018-1065.NASL | description | According to the versions of the quagga package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :
- A double-free vulnerability was found in Quagga. A BGP
peer could send a specially crafted UPDATE message
which would cause allocated blocks of memory to be
free()d more than once, potentially leading to a crash
or other issues.(CVE-2018-5379)
- 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.(CVE-2017-5495)

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The quagga packages contain Quagga, the free network-routing software
suite that manages TCP/IP based protocols. Quagga supports the BGP4,
BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng protocols, and is
intended to be used as a Route Server and Route Reflector.
Security Fix(es) :
* A stack-based buffer overflow flaw was found in the way Quagga
handled IPv6 router advertisement messages. A remote attacker could
use this flaw to crash the zebra daemon resulting in denial of
service. (CVE-2016-1245)
* A stack-based buffer overflow flaw was found in the way the Quagga
BGP routing daemon (bgpd) handled Labeled-VPN SAFI routes data. A
remote attacker could use this flaw to crash the bgpd daemon resulting
in denial of service. (CVE-2016-2342)
* A denial of service flaw was found in the Quagga BGP routing daemon
(bgpd). Under certain circumstances, a remote attacker could send a
crafted packet to crash the bgpd daemon resulting in denial of
service. (CVE-2016-4049)
* A denial of service flaw affecting various daemons in Quagga was
found. A remote attacker could use this flaw to cause the various
Quagga daemons, which expose their telnet interface, to crash.
(CVE-2017-5495)
* A stack-based buffer overflow flaw was found in the way the Quagga
OSPFD daemon handled LSA (link-state advertisement) packets. A remote
attacker could use this flaw to crash the ospfd daemon resulting in
denial of service. (CVE-2013-2236)
