![]() If they point outside this area, the buffer itself may be moved while the byte reference stays the same. NET garbage collector can only update these byte references if they still point within the buffer or to a point one byte past the end of the buffer. However, when the garbage collector performs compaction and rearranges memory, it must update any byte references on the stack to refer to the updated location. This change generally improves performance and reduces workload on the garbage collector. In this release, much of the code was rewritten to use byte references rather than pointers to pinned buffers. ![]() This is a buffer overrun vulnerability that can affect any user of Snappier 1.1.0. Snappier is a high performance C# implementation of the Snappy compression algorithm. fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_create_hw_instance : Status:104 Could not program dfw(lo0.0-inet6-i) type(IFP_DFLT_INET6_Lo0_FILTER)! fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_bind_shim : Could not create dfw(lo0.0-inet6-i) type(IFP_DFLT_INET6_Lo0_FILTER) fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_update_resolve : Failed to bind filter(3) to bind point fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_change_end : dnx_dfw_update_resolve (resolve type) failed This issue affects Juniper Networks Junos OS on ACX Series: All versions prior to 20.2R3-S7 20.4 versions prior to 20.4R3-S4 21.1 versions prior to 21.1R3-S3 21.2 versions prior to 21.2R3-S4 21.3 versions prior to 21.3R3 21.4 versions prior to 21.4R3 22.1 versions prior to 22.1R2. An indication that the filter was not installed can be identified with the following logs: fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_rule_prepare : Config failed: Unsupported Ip-protocol 51 in the filter lo0.0-inet6-i fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_rule_prepare : Please detach the filter, remove unsupported match and re-attach fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_process_rule : Status:104 dnx_dfw_rule_prepare failed fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_process_filter : Status:104 dnx_dfw_process_rule failed fpc0 ACX_DFW_CFG_FAILED: ACX Error (dfw):dnx_dfw_update_filter_in_hw : Status:104 Could not process filter(lo0.0-inet6-i) for rule expansion Unsupported match, action present. ![]() There is no immediate indication of an incomplete firewall filter commit shown at the CLI, which could allow an attacker to send valid packets to or through the device that were explicitly intended to be dropped. As a workaround, delete the offending keyspace using a CLI client (vtctldclient).Īn Improper Handling of Unexpected Data Type vulnerability in IPv6 firewall filter processing of Juniper Networks Junos OS on the ACX Series devices will prevent a firewall filter with the term 'from next-header ah' from being properly installed in the packet forwarding engine (PFE). Note that all other keyspaces can still be administered using the CLI (vtctldclient). Trying to list all the keyspaces using `vtctldclient GetKeyspaces` will also return an error. ![]() Users can either intentionally or inadvertently create a keyspace containing `/` characters such that from that point on, anyone who tries to view keyspaces from VTAdmin will receive an error.
