CWE-120

4,537 CVEs • Abstraction: Base • Likelihood of Exploit: High

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.

A flaw has been found in Edimax BR-6208AC 1.32. Affected by this issue is some unknown functionality of the file /goform/formWlSiteSurvey. This manipulation of the argument ifname causes buffer overflow. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.Show less

A vulnerability was detected in Kamailio up to 6.0.7/6.1.3. The affected element is the function isup_get_calling_party of the file src/modules/sipt/ss7_parser.c of the component sipt Module. The manipulation of the argument length results in buffer overflow. The attack may be performed from remote. Upgrading to version 6.0.8 and 6.1.4 is sufficient to fix this issue. The patch is identified as 3667bebf8d0bea07ed16218fd921d07db87aeb21. Upgrading the affected component is advised.Show less

The LE Audio Broadcast Sink in subsys/bluetooth/audio/bap_broadcast_sink.c copies subgroup metadata from a received Basic Audio Announcement (BASE) into the static Broadcast Audio Scan Service parameter structure mod_src_param without any bounds check. In base_subgroup_meta_cb() the destination element was selected as mod_src_param.subgroups[mod_src_param.num_subgroups] with no test against ARRAY_SIZE(mod_src_param.subgroups) (sized by CONFIG_BT_BAP_BASS_MAX_SUBGROUPS, default 1), and the metadata was copied with memcpy() using the raw on-air length returned by bt_bap_base_get_subgroup_codec_meta() into a metadata array sized by CONFIG_BT_AUDIO_CODEC_CFG_MAX_METADATA_SIZE (default 4). The BASE validator bt_bap_base_get_base_from_ad() only checks structural consistency and permits up to ~24 subgroups and metadata LTVs of ~240 octets. The defect is reached from the periodic advertising receive callback: pa_recv() → bt_data_parse() → pa_decode_base() → update_recv_state_base() → bt_bap_base_foreach_subgroup() → base_subgroup_meta_cb(). Every broadcast sink registers a scan-delegator receive state at creation (bt_bap_broadcast_sink_create() calls broadcast_sink_add_src()), and CONFIG_BT_BAP_BROADCAST_SINK depends on CONFIG_BT_BAP_SCAN_DELEGATOR, so the path is active in every broadcast-sink build once the device is periodic-advertising-synced. An attacker in radio range who operates a broadcast source the device syncs to — or who impersonates the advertiser address and SID of one already in use, periodic advertising data being unauthenticated — can change the BASE at will; each new BASE is re-parsed. A crafted BASE therefore writes attacker-chosen bytes past the end of a fixed static object in .bss: up to roughly 236 bytes for an oversized metadata LTV, plus whole struct bt_bap_bass_subgroup records for each subgroup beyond CONFIG_BT_BAP_BASS_MAX_SUBGROUPS. This is memory corruption of adjacent Bluetooth-audio state reachable with no pairing, bonding or GATT connection, with a potential for remote code execution in the Bluetooth RX thread; in addition, the unvalidated metadata_len is forwarded to bt_bap_scan_delegator_mod_src(), which neither clamps it nor rejects it, leading to a further copy into the receive state and to out-of-bounds memory being disclosed in the BASS receive-state notification sent to a connected Broadcast Assistant. The fix rejects a BASE carrying more subgroups than the receive state can hold (discarding the update entirely) and omits metadata that does not fit rather than copying it, and additionally honours the previously-ignored error return of the subgroup decode pass.Show less

A memory buffer overflow vulnerability exists in the internal diagnostic and route validation routines used by the Fabric Shortest Path First (FSPF) protocol component of Brocade Fabric OS versions before 10.0.1. While this code path is part of internal diagnostic functionality and is not directly accessible via standard user interfaces or CLI management commands, an input processing flaw allows incoming or internally routed diagnostic state payloads to exceed allocated memory boundaries. An attacker that is able to chain or link other vulnerabilities to exploit this internal diagnostic could cause a heap- or stack-based memory overrun, resulting in a daemon crash (Denial of Service) or potential arbitrary code execution within the context of the routing daemon.Show less
