CVE-2015-3209 8 Arista, Canonical, Debian and 5 more 20 Eos, Ubuntu Linux, Debian Linux and 17 more 2024-08-06 N/A
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set.
CVE-2015-3214 6 Arista, Debian, Lenovo and 3 more 20 Eos, Debian Linux, Emc Px12-400r Ivx and 17 more 2024-08-06 N/A
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.
CVE-2017-18017 9 Arista, Canonical, Debian and 6 more 33 Eos, Ubuntu Linux, Debian Linux and 30 more 2024-08-05 9.8 Critical
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.

CVE-2018-14008 1 Arista 1 Eos 2024-08-05 N/A
Arista EOS through 4.21.0F allows a crash because 802.1x authentication is mishandled.

CVE-2019-18948 1 Arista 1 Eos 2024-08-05 7.5 High
An issue was found in Arista EOS. Specific malformed ARP packets can impact the software forwarding of VxLAN packets. This issue is found in Arista’s EOS VxLAN code, which can allow attackers to crash the VxlanSwFwd agent. This affects EOS 4.21.8M and below releases in the 4.21.x train, 4.22.3M and below releases in the 4.22.x train, 4.23.1F and below releases in the 4.23.x train, and all releases in 4.15, 4.16, 4.17, 4.18, 4.19, 4.20 code train.
CVE-2019-17596 6 Arista, Debian, Fedoraproject and 3 more 13 Cloudvision Portal, Eos, Mos and 10 more 2024-08-05 7.5 High
Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates.
CVE-2020-26569 1 Arista 47 7010t-48, 7050cx3-32s, 7050cx3m-32s and 44 more 2024-08-04 5.9 Medium
In EVPN VxLAN setups in Arista EOS, specific malformed packets can lead to incorrect MAC to IP bindings and as a result packets can be incorrectly forwarded across VLAN boundaries. This can result in traffic being discarded on the receiving VLAN. This affects versions: 4.21.12M and below releases in the 4.21.x train; 4.22.7M and below releases in the 4.22.x train; 4.23.5M and below releases in the 4.23.x train; 4.24.2F and below releases in the 4.24.x train.
CVE-2020-25686 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2024-08-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the "Birthday Attacks" section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25684 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2024-08-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25685 5 Arista, Debian, Fedoraproject and 2 more 10 Eos, Debian Linux, Fedora and 7 more 2024-08-04 3.7 Low
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-24360 1 Arista 27 7280cr2ak-30, 7280cr2k-60, 7280cr3-32d4 and 24 more 2024-08-04 7.4 High
An issue with ARP packets in Arista’s EOS affecting the 7800R3, 7500R3, and 7280R3 series of products may result in issues that cause a kernel crash, followed by a device reload. The affected Arista EOS versions are: 4.24.2.4F and below releases in the 4.24.x train; 4.23.4M and below releases in the 4.23.x train; 4.22.6M and below releases in the 4.22.x train.
CVE-2020-17355 1 Arista 1 Eos 2024-08-04 7.5 High
Arista EOS before 4.21.12M, 4.22.x before 4.22.7M, 4.23.x before 4.23.5M, and 4.24.x before 4.24.2F allows remote attackers to cause a denial of service (restart of agents) by crafting a malformed DHCP packet which leads to an incorrect route being installed.
CVE-2020-15897 1 Arista 1 Eos 2024-08-04 7.5 High
Arista EOS before 4.21.12M, 4.22.x before 4.22.7M, 4.23.x before 4.23.5M, and 4.24.x before 4.24.2F allows remote attackers to cause traffic loss or incorrect forwarding of traffic via a malformed link-state PDU to the IS-IS router.
CVE-2020-15898 1 Arista 49 7050cx3-32s, 7050cx3m-32s, 7050qx-32s and 46 more 2024-08-04 5.3 Medium
In Arista EOS malformed packets can be incorrectly forwarded across VLAN boundaries in one direction. This vulnerability is only susceptible to exploitation by unidirectional traffic (ex. UDP) and not bidirectional traffic (ex. TCP). This affects: EOS 7170 platforms version 4.21.4.1F and below releases in the 4.21.x train; EOS X-Series versions 4.21.11M and below releases in the 4.21.x train; 4.22.6M and below releases in the 4.22.x train; 4.23.4M and below releases in the 4.23.x train; 4.24.2.1F and below releases in the 4.24.x train.
CVE-2020-10188 7 Arista, Debian, Fedoraproject and 4 more 10 Eos, Debian Linux, Fedora and 7 more 2024-08-04 9.8 Critical
utility.c in telnetd in netkit telnet through 0.17 allows remote attackers to execute arbitrary code via short writes or urgent data, because of a buffer overflow involving the netclear and nextitem functions.
CVE-2021-28510 1 Arista 77 7020r, 7050cx3-32s, 7050cx3m-32s and 74 more 2024-08-03 5.3 Medium
For certain systems running EOS, a Precision Time Protocol (PTP) packet of a management/signaling message with an invalid Type-Length-Value (TLV) causes the PTP agent to restart. Repeated restarts of the service will make the service unavailable.
CVE-2021-28504 1 Arista 18 Ccs-710p-12, Ccs-710p-16p, Ccs-720xp-24y6 and 15 more 2024-08-03 7.5 High
On Arista Strata family products which have “TCAM profile” feature enabled when Port IPv4 access-list has a rule which matches on “vxlan” as protocol then that rule and subsequent rules ( rules declared after it in ACL ) do not match on IP protocol field as expected.
