CVE-2026-67293 FreeRDP before 3.29.0 Improper Certificate Hostname Validation

FreeRDP before 3.29.0 affected versions = 3.28.0 contains an improper certificate hostname validation vulnerability. The TLS hostname matcher tlsmatchhostname in libfreerdp/crypto/tls.c treats a wildcard pattern such as .example.com as matching any hostname ending in .example.com, so it incorrect...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

CVE-2026-13117

A flaw was found in OpenVPN. An incomplete guard allows remote authenticated peers to trigger a use-after-free vulnerability during TLS Transport Layer Security session promotion. This can lead to a denial of service, making the service unavailable, or memory leakage, which could potentially expo...

CVE-2026-12996

A flaw was found in OpenVPN. This use-after-free vulnerability allows remote authenticated peers to send specially crafted packets during TLS Transport Layer Security session promotion or expiry. Successful exploitation of this flaw could lead to a denial of service, making the service unavailabl...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the GOOSE payload parser. An attacker can cause the subscriber process to terminate by sending a specially crafted unauthenticated Layer 2 multicast frame with an attacker-controlled inner element length that...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the processing of encoded presentation data in the ISO Presentation layer. An attacker can cause the process to terminate by sending a crafted TCP/102 connection attempt with a controlled field set to a zero lengt...

SUSE CVE-2025-71261

An attacker with network-level access between the SUSE Virtualization and Rancher Manager in SUSE Harvester before 1.8.0 could interfere with the TLS handshake and abuse it to bypass TLS as a security control...

SUSE CVE-2026-4370

A vulnerability was identified in Juju from version 3.2.0 until 3.6.19 and from version 4.0 until 4.0.4, where the internal Dqlite database cluster fails to perform proper TLS client and server authentication. Specifically, the Juju controller's database endpoint does not validate client...

SUSE CVE-2026-7776

Boundary Community Edition and Boundary Enterprise “Boundary” workers are vulnerable to a denial-of-service condition during node enrollment TLS handshakes. An attacker with network access to the worker authentication listener may open a connection and delay or withhold the client certificate...

EUVD-2026-51359

The GOOSE subscriber component improperly validates the UTC timestamp field in unauthenticated IEC 61850 GOOSE EtherType 0x88B8 Layer-2 multicast messages. A specially crafted GOOSE frame containing an undersized timestamp field can trigger a heap out-of-bounds read during message processing,...

EUVD-2026-51339

The ACSE layer contains a flaw in the processing of AARQ PDUs during MMS connection establishment. When parsing certain fields within the calling AP title, an attacker controlled length value of zero or one may cause the parser to read past the end of a heap buffer...

EUVD-2026-51338

The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This...

EUVD-2026-51341

The GOOSE payload parser contains a boundary handling flaw that can be triggered by a single unauthenticated Layer 2 multicast frame on the process bus. When processing specific payload fields, an attacker controlled inner element length may exceed its enclosing length, causing the parser to over...

CVE-2026-66360

The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This...
