CVE-2026-51536

OpENer 2.3.0 is affected by CVE-2026-51536 due to inconsistent typing of the length parameter across the call stack: an upstream int length is passed to a downstream function expecting a 16-bit signed EipInt16. A crafted CIP packet can cause the length to overflow or become negative, bypassing bo...

CVE-2026-51536

In OpENer 2.3.0 commit 76b95cf when parsing incoming CIP Common Industrial Protocol network packets, the length parameter is inconsistently typed across the call stack. Specifically, an upstream length calculated as an int is passed to a downstream function that expects an EipInt16 a 16-bit signe...

CVE-2026-43994

A flaw was found in Coturn, an open-source TURN and STUN server. A remote attacker can exploit a stack buffer overflow vulnerability by providing a specially crafted OAuth access token when the server is configured to use --oauth mode. This could lead to arbitrary code execution RCE, allowing the...

GHSA-VC8P-8PXG-RFWG ConnectBot SSH Client Library: Excessive allocation and integer overflow in DER private-key parsing

Summary The DER parser used for application-supplied private keys did not safely validate encoded length values before converting them to Int values or allocating arrays. A malformed private-key file could encode a length that overflowed or wrapped around, or request an allocation much larger tha...
