tomcat: Client certificate verification bypass due to virtual host mapping

A certificate validation flaw has been found in Apache Tomcat. omcat did not validate that the host name provided via the SNI extension was the same as the host name provided in the HTTP host header field. If Tomcat was configured with more than one virtual host and the TLS configuration for one ...

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-2026-42505

CVE-2026-42505 describes a privacy leakage in handshakes using Encrypted Client Hello (ECH) , where a passive observer can de-anonymize connections due to disclosure of pre-shared key (PSK) identities in the unencrypted ClientHello. The vulnerability is documented across multiple sources (NVD, EU...

389-ds-base: 389-ds-base: integer overflow in SASL packet length bypasses size limit leading to heap buffer overflow

An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, adding sizeofuint32t to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer...

Astra Linux – Vulnerability in exim4

In versions of Exim prior to 4.99.3, and under certain GnuTLS configurations, there is a remotely reachable use-after-free in the BDAT body parsing path. This issue is triggered when a client sends a TLS closenotify message during a CHUNKING transfer, followed by a final cleartext byte on the sam...

Astra Linux – Vulnerability in Network-Manager

A flaw was discovered in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. This would cause NetworkManager to crash, resulting in a denial of service...

389-ds-base: 389-ds-base: Heap buffer overflow in sasl_io_recv() via padded SASL UNBIND

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. After a successful SASL bind with integrity protection SSF 0, an authenticated attacker can send a specially crafted oversized LDAP UNBIND packet that is copied into a 512-byte heap receive buffer...

CVE-2026-12479

A flaw was found in Keras, specifically in the model saving and loading library.
