CVE-2021-44038 1 Quagga 1 Quagga 2024-02-28 7.2 HIGH 7.8 HIGH
An issue was discovered in Quagga through 1.2.4. Unsafe chown/chmod operations in the suggested spec file allow users (with control of the non-root-owned directory /etc/quagga) to escalate their privileges to root upon package installation or update.
CVE-2012-5521 3 Debian, Quagga, Redhat 3 Debian Linux, Quagga, Enterprise Linux 2024-02-28 3.3 LOW 6.5 MEDIUM
quagga (ospf6d) 0.99.21 has a DoS flaw in the way the ospf6d daemon performs routes removal
CVE-2017-3224 3 Quagga, Redhat, Suse 4 Quagga, Package Manager, Opensuse and 1 more 2024-02-28 4.3 MEDIUM 8.2 HIGH
Open Shortest Path First (OSPF) protocol implementations may improperly determine Link State Advertisement (LSA) recency for LSAs with MaxSequenceNumber. According to RFC 2328 section 13.1, for two instances of the same LSA, recency is determined by first comparing sequence numbers, then checksums, and finally MaxAge. In a case where the sequence numbers are the same, the LSA with the larger checksum is considered more recent, and will not be flushed from the Link State Database (LSDB). Since the RFC does not explicitly state that the values of links carried by a LSA must be the same when prematurely aging a self-originating LSA with MaxSequenceNumber, it is possible in vulnerable OSPF implementations for an attacker to craft a LSA with MaxSequenceNumber and invalid links that will result in a larger checksum and thus a 'newer' LSA that will not be flushed from the LSDB. Propagation of the crafted LSA can result in the erasure or alteration of the routing tables of routers within the routing domain, creating a denial of service condition or the re-routing of traffic on the network. CVE-2017-3224 has been reserved for Quagga and downstream implementations (SUSE, openSUSE, and Red Hat packages).
CVE-2018-5378 3 Canonical, Debian, Quagga 3 Ubuntu Linux, Debian Linux, Quagga 2024-02-28 4.9 MEDIUM 5.9 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 does not properly bounds check the data sent with a NOTIFY to a peer, if an attribute length is invalid. Arbitrary data from the bgpd process may be sent over the network to a peer and/or bgpd may crash.
CVE-2018-5381 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
The Quagga BGP daemon (bgpd) prior to version 1.2.3 has a bug in its parsing of "Capabilities" in BGP OPEN messages, in the bgp_packet.c:bgp_capability_msg_parse function. The parser can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI, causing a denial of service.
CVE-2018-5380 4 Canonical, Debian, Quagga and 1 more 5 Ubuntu Linux, Debian Linux, Quagga and 2 more 2024-02-28 4.0 MEDIUM 4.3 MEDIUM
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value, based on input.
CVE-2018-5379 5 Canonical, Debian, Quagga and 2 more 10 Ubuntu Linux, Debian Linux, Quagga and 7 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
The Quagga BGP daemon (bgpd) prior to version 1.2.3 can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes. A successful attack could cause a denial of service or potentially allow an attacker to execute arbitrary code.
CVE-2017-16227 2 Debian, Quagga 2 Debian Linux, Quagga 2024-02-28 5.0 MEDIUM 7.5 HIGH
The aspath_put function in bgpd/bgp_aspath.c in Quagga before 1.2.2 allows remote attackers to cause a denial of service (session drop) via BGP UPDATE messages, because AS_PATH size calculation for long paths counts certain bytes twice and consequently constructs an invalid message.
CVE-2016-1245 2 Debian, Quagga 2 Debian Linux, Quagga 2024-02-28 7.5 HIGH 9.8 CRITICAL
It was discovered that the zebra daemon in Quagga before 1.0.20161017 suffered from a stack-based buffer overflow when processing IPv6 Neighbor Discovery messages. The root cause was relying on BUFSIZ to be compatible with a message size; however, BUFSIZ is system-dependent.
CVE-2017-5495 1 Quagga 1 Quagga 2024-02-28 7.8 HIGH 7.5 HIGH
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.
CVE-2016-2342 2 Debian, Quagga 2 Debian Linux, Quagga 2024-02-28 7.6 HIGH 8.1 HIGH
The bgp_nlri_parse_vpnv4 function in bgp_mplsvpn.c in the VPNv4 NLRI parser in bgpd in Quagga before 1.0.20160309, when a certain VPNv4 configuration is used, relies on a Labeled-VPN SAFI routes-data length field during a data copy, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted packet.
CVE-2016-4049 2 Opensuse, Quagga 3 Leap, Opensuse, Quagga 2024-02-28 5.0 MEDIUM 7.5 HIGH
The bgp_dump_routes_func function in bgpd/bgp_dump.c in Quagga does not perform size checks when dumping data, which might allow remote attackers to cause a denial of service (assertion failure and daemon crash) via a large BGP packet.
CVE-2012-1820 1 Quagga 1 Quagga 2024-02-28 2.9 LOW N/A
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.
CVE-2013-2236 1 Quagga 1 Quagga 2024-02-28 2.6 LOW N/A
Stack-based buffer overflow in the new_msg_lsa_change_notify function in the OSPFD API (ospf_api.c) in Quagga before 0.99.22.2, when --enable-opaque-lsa and the -a command line option are used, allows remote attackers to cause a denial of service (crash) via a large LSA.
CVE-2013-6051 1 Quagga 1 Quagga 2024-02-28 4.3 MEDIUM N/A
The bgp_attr_unknown function in bgp_attr.c in Quagga 0.99.21 does not properly initialize the total variable, which allows remote attackers to cause a denial of service (bgpd crash) via a crafted BGP update.
CVE-2012-0249 1 Quagga 1 Quagga 2024-02-28 3.3 LOW N/A
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-2012-0250 1 Quagga 1 Quagga 2024-02-28 3.3 LOW N/A
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-2012-0255 1 Quagga 1 Quagga 2024-02-28 5.0 MEDIUM N/A
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-2011-3323 1 Quagga 1 Quagga 2024-02-28 5.0 MEDIUM N/A
The OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (out-of-bounds memory access and daemon crash) via a Link State Update message with an invalid IPv6 prefix length.
CVE-2011-3326 1 Quagga 1 Quagga 2024-02-28 5.0 MEDIUM N/A
The ospf_flood function in ospf_flood.c in ospfd in Quagga before 0.99.19 allows remote attackers to cause a denial of service (daemon crash) via an invalid Link State Advertisement (LSA) type in an IPv4 Link State Update message.
