| A security flaw has been discovered in yangzongzhuan RuoYi up to 4.8.3. Impacted is the function VelocityUtils.getFileName of the file VelocityUtils.java of the component Code Generator. Performing a manipulation of the argument className results in path traversal. The attack is possible to be carried out remotely. |
| In FRRouting, bgpd frees the same memory twice when dynamic BGP neighbors disconnect, if the peer-group used by a "bgp listen range" also has a Site-of-Origin configured ("neighbor PG soo"). Each dynamic neighbor shares the peer-group's SoO value instead of getting its own copy, but frees it as its own when the neighbor is deleted, which happens as soon as its connection closes. The first disconnect leaves the peer-group pointing at freed memory, and the second disconnect frees it again, causing bgpd to abort and drop all BGP sessions on the router. Any host whose address falls inside the listen range can trigger this by opening and closing two TCP connections to the BGP port, without sending any BGP message and without knowing the AS number, and can repeat it each time bgpd restarts. If the peer-group has a TCP-MD5 password, only hosts that know the password can trigger it. Two ordinary flaps of legitimate dynamic neighbors have the same effect. Between the two frees, displaying the configuration ("show running-config") or establishing a dynamic neighbor also reads the freed memory, which can crash bgpd after a single disconnect. Only configurations that combine a listen range with a SoO on the same peer-group are affected. |
| In FRRouting, bgpd does not correctly close a BGP session when the Send Hold Timer (RFC 9687) expires, i.e. when a neighbor has stopped accepting data from the router for twice the hold time. The connection is closed, but bgpd still considers the session to be up. A BGP neighbor that keeps sending KEEPALIVEs but stops reading from its connection, at a time when the router has a large amount of data to send to it (for example while sending it a full routing table), can trigger this. If the neighbor announced Graceful Restart support, bgpd crashes shortly after the session is closed, taking down all BGP sessions on the router, and the neighbor can repeat this each time bgpd restarts. Otherwise, the session stays stuck in the Established state: the neighbor's routes stay installed and keep being advertised to other peers, and the neighbor cannot reconnect until an operator clears the session manually. The neighbor does not need to be malicious; an overloaded or stuck peer can trigger the same behavior. No special configuration is required: any established BGP neighbor can trigger the issue, and Graceful Restart helper mode, which leads to the crash, is enabled by default. |

| In the Linux kernel, the following vulnerability has been resolved:
xen-netback: Fix XenBus connection failure cleanup
xenvif_get_stats and xenvif_get_ethtool_stats capture vif->num_queues
under rcu_read_lock. We need to unpublish vif->num_queues before
synchronize_net to ensure that readers that come afterwards will not
read a non-zero vif->num_queues and attempt to access invalid queues.
This is the same cleanup algorithm as used in backend_disconnect and
added in commit b17075d5c198 ("xen-netback: fix race condition on XenBus
disconnect").
This is XSA-531 |
| In the Linux kernel, the following vulnerability has been resolved:
xen-netback: Zero out sring pointers on unmap
If xenvif_map_frontend_data_rings() fails when a ring is already mapped,
it unmaps them via xenvif_unmap_frontend_data_rings() which keeps the
ring pointers unchanged. xenvif_connect_data()'s cleanup path calls
xenvif_disconnect_queue() which in turn calls
xenvif_unmap_frontend_data_rings() again, which will attempt to unmap the
pointers a second time.
Zero out the ring pointers after they are unmapped to avoid this issue.
This is XSA-532 |
