FRRouting < 10.5.3 Integer Overflow in OSPF TLV Parser Functions
A vulnerability has been found in FRRouting FRR up to 10.5.1. This affects the function processtype2route of the file bgpd/bgpevpn.c of the component EVPN Type-2 Route Handler. The manipulation leads to improper access controls. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitability is reported as difficult. The identifier of the patch is 7676cad65114aa23adde583d91d9d29e2debd045. To fix this issue, it is recommended to deploy a patch.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyextprefprefsid function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted LSA Update packet.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyunknowntlv function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyextprefprefsid function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyextlinklanadjsid function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the opaqueinfodetail function at ospfopaque.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted LS Update packet.
FRRouting/frr from v2.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the ospfopaquelsadump function at ospfopaque.c. This vulnerability allows attackers to cause a Denial of Service (DoS) under specific malformed LSA conditions.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtylinkinfo function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyextlinkrmtitfaddr function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
FRRouting/frr from v4.0 through v10.4.1 was discovered to contain a NULL pointer dereference via the showvtyextlinkadjsid function at ospfext.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted OSPF packet.
In FRRouting (FRR) all routes are re-validated if the total size of an update received via RTR exceeds the internal socket's buffer size
An issue was discovered in FRRouting (FRR) through 10.1. bgpattrencap in bgpd/bgpattr.c does not check the actual remaining stream length before taking the TLV value.
In FRRouting (FRR) through 9.1 it is possible for the getedge() function in ospfte.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value the OSPF daemon crashes leading to denial of service.
In FRRouting (FRR) through 9.1, an infinite loop can occur when receiving a MP/GR capability as a dynamic capability because malformed data results in a pointer not advancing.
In the Opaque LSA Extended Link parser in FRRouting (FRR) through 9.1 there can be a buffer overflow and daemon crash in ospfteparseextlink for OSPF LSA packets during an attempt to read Segment Routing Adjacency SID subTLVs (lengths are not validated).
In FRRouting (FRR) through 9.1, an attacker using a malformed Prefix SID attribute in a BGP UPDATE packet can cause the bgpd daemon to crash.
In FRRouting (FRR) through 9.1 there can be a buffer overflow and daemon crash in ospfteparseri for OSPF LSA packets during an attempt to read Segment Routing subTLVs (their size is not validated).
ospfteparsete in ospfd/ospfte.c in FRRouting (FRR) through 9.1 allows remote attackers to cause a denial of service (ospfd daemon crash) via a malformed OSPF LSA packet, because of an attempted access to a missing attribute field.
bgpd/bgpflowspec.c in FRRouting (FRR) before 8.4.3 mishandles an nlri length of zero, aka a "flowspec overflow."
bgpd/bgplabel.c in FRRouting (FRR) before 8.5 attempts to read beyond the end of the stream during labeled unicast parsing.
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when processing a crafted BGP UPDATE message with a MPUNREACHNLRI attribute and additional NLRI data (that lacks mandatory path attributes).
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when a malformed BGP UPDATE message with an EOR is processed, because the presence of EOR does not lead to a treat-as-withdraw outcome.
