Stack-based buffer overflow in Windows Netlogon allows an unauthorized attacker to execute code over a network.
CVE-2026-40950 1 Absolute 1 Secure Access 2026-06-17 N/A 6.5 MEDIUM
CVE-2026-40950 is a buffer overflow vulnerability in the Secure Access server prior to 14.50. Attackers with control of a modified client can send a specially crafted message to the server and cause a denial of service
CVE-2026-40949 2 Absolute, Microsoft 2 Secure Access, Windows 2026-06-17 N/A 4.4 MEDIUM
CVE-2026-40949 is a buffer overflow vulnerability in the Secure Access Windows client prior to 14.50. Attackers with local control of the Windows client can use it to trigger a denial of service.
CVE-2026-40892 1 Pjsip 1 Pjsip 2026-06-17 N/A 9.8 CRITICAL
PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, a stack buffer overflow exists in pjsip_auth_create_digest2() in PJSIP when using pre-computed digest credentials (PJSIP_CRED_DATA_DIGEST). The function copies credential data using cred_info->data.slen as the length without an upper-bound check, which can overflow the fixed-size ha1 stack buffer (128 bytes) if data.slen exceeds the expected digest string length.
CVE-2026-40528 1 Opensc Project 1 Opensc 2026-06-17 N/A 3.8 LOW
OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.
CVE-2026-40510 1 Opensc Project 1 Opensc 2026-06-17 N/A 3.8 LOW
OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than 118 bytes in the Key History Object ASN.1 response.
CVE-2026-40489 2026-06-17 N/A N/A
editorconfig-core-c is an EditorConfig core library for use by plugins supporting EditorConfig parsing. Versions up to and including 0.12.10 have a stack-based buffer overflow in ec_glob() that allows an attacker to crash any application using libeditorconfig by providing a specially crafted directory structure and .editorconfig file. This is an incomplete fix for CVE-2023-0341. The pcre_str buffer was protected in 0.12.6 but the adjacent l_pattern[8194] stack buffer received no equivalent protection. On Ubuntu 24.04, FORTIFY_SOURCE converts the overflow to SIGABRT (DoS). Version 0.12.11 contains an updated fix.
CVE-2026-40399 1 Microsoft 13 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 10 more 2026-06-17 N/A 7.8 HIGH
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows TCP/IP allows an authorized attacker to elevate privileges locally.
CVE-2026-40170 1 Tatsuhiro-t 1 Ngtcp2 2026-06-17 N/A 7.5 HIGH
ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately upgrade, they can disable the qlog on client.
CVE-2026-3978 1 Dlink 2 Dir-513, Dir-513 Firmware 2026-06-17 9.0 HIGH 8.8 HIGH
