OpenVPN version 2.1.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows attackers via an off-by-one buffer write in the NTLM proxy authentication to potentially cause a crash via a crafted NTLM response from a malicious proxy server

CVE-2026-9408910.0 CRI—
———A vulnerability was determined in D-Link DIR-868L 2.01b05. This issue affects the function strcpy of the file /webfa_authentication.cgi of the component Authentication Handler. Executing a manipulation of the argument id/password can lead to stack-based buffer overflow. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized.9hCVE-2026-9400310.0 CRI—
——0A vulnerability has been found in Comfast CF-N1-S 2.6.0.1. Impacted is the function get_css_path_from_uri of the file /cgi-bin/mbox-config of the component Web Management Interface. The manipulation leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.18hCVE-2026-940547.0 HIG20.0%
——6Exim before 4.100.1, when Proxy-Protocol is used with an attacker-controlled proxy, has an out-of-bounds write.1dCVE-2026-93894—16.7%
——5In Vinyl Cache before 9.0,2, workspace buffer overflow vulnerability was found in the .upper() and .lower() string type methods of VCL. This can be used as a remote denial of service (DoS) vector to make the child process segfault or assert, and then restart. Effectively exploiting this vulnerability requires prior knowledge about the VCL in use and the ability to craft a request that contains a string that is long enough to fill the remaining workspace at the call site while staying under the different request size limits (http_req_size, http_req_hdr_len, etc.).2dCVE-2026-617147.8 HIG4.0%
——1FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.2.4 until 2.5.6, configuring synth.midi-channels above 16 allows the MIDI player to index _fluid_player_t::channel_isplaying outside its fixed-size heap allocation while tracking active channels. The resulting out-of-bounds reads and writes invoke undefined behavior and may compromise confidentiality, integrity, or availability. No crafted MIDI file is required because the unsafe condition is created by the channel-count configuration itself. Keeping synth.midi-channels at its default value of 16 avoids the vulnerable path. This issue is fixed in version 2.5.6.2dCVE-2026-75892—3.7%
——1In osmo-ggsn 1.14.0 an out of bounds write issue was found in the gtp_decode_pdp_ctx() function through the PDP context GSN-Address sub-field, leading to memory corruption.2d
