psqlODBC copies the reply to a large-object read (loread) into the application's buffer using the length sent by the server, without comparing it to the buffer size. A server not trusted under current SSL settings, or a man-in-the-middle, can return more bytes than the buffer holds and overwrite adjacent memory in the client process with server-chosen bytes. Fetching any large-object column is sufficient to trigger it. Versions before psqlODBC 18.00.0006 are affected.

CVE-2026-769558.8 ALT—
———A buffer overflow vulnerability in the zdp_wtp binary in Zyxel NWA110AX firmware versions through 7.12(ABTG.0)C0 could allow a LAN-based attacker to escalate privileges on an affected device.8hCVE-2026-1068047.5 ALT—
———A stack-based buffer overflow exists in Kamailio v6.1.3 and v6.1.4 in the ims_qos_npn module. The w_rx_aar_register() function copies the attacker-controlled host field from the SIP `Via` header into a fixed 46-byte stack buffer without validating its length. An unauthenticated remote attacker can trigger the vulnerability with a crafted SIP `REGISTER` request, causing stack corruption and termination of the affected Kamailio instance, resulting in denial of service.15hCVE-2026-1202417.5 ALT—
——0A vulnerability was identified in Ruijie RG-ES205GC, RG-ES206GC-P, RG-ES208GC, RG-ES210GC-LP and RG-ES210GS-P ESW_1.0(1)B1P48. Impacted is an unknown function of the file httpupg.cgi of the component Local Firmware Upgrade Interface. The manipulation leads to buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.18hCVE-2026-1202263.3 BAJ—
——0A security vulnerability has been detected in Hangzhou Xiongmai Technology P2PAPI.dll 1.3.3.32 on Windows. Affected by this issue is the function P2PAPI_Connect of the component P2P SDK. Such manipulation of the argument input as part of String leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.18hCVE-2026-1191465.6 MED39.8%
——12ProFTPD before 1.3.9e and 1.3.10rc5 contains a buffer overflow vulnerability in the mod_rewrite int:utf8trans RewriteMap that allows remote attackers to overwrite static buffers. Attackers can send FTP command arguments longer than 1024 bytes, without authentication if pre-login commands are rewritten, to corrupt session memory and crash the session.4dCVE-2026-57191—48.3%
——14Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an unbounded `sscanf` in `res_pjsip_pubsub` when parsing the `MWI NOTIFY` `Message-Account` field may allow an unauthenticated attacker to send a carefully crafted packet that causes a stack buffer overflow and corrupts the underlying transport, permanently disabling all SIP functionality. An Asterisk restart is required to restore full operation. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.14h
