Astra Linux – Vulnerability in PostgresSQL 11

When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries during the initial establishment of a connection, despite the use of SSL certificate verification and encryption...

Astra Linux – Vulnerability in Thunderbird

Thunderbird ignored the configuration that required STARTTLS security for SMTP connections. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication...

Astra Linux – Vulnerability in libgit2

libgit2 is a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Previous versions of libgit2 required the caller to set the certificatecheck field of the libgit2’s...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-6.1, Linux-5.10

Bluetooth BR/EDR devices with Secure Simple Pairing and Secure Connections support pairing in Bluetooth Core Specification 4.2 through 5.4. However, these devices are vulnerable to certain man-in-the-middle attacks, which force the use of a short key length. This vulnerability may lead to the...

CVE-2026-12566 SSRF via unvalidated WWW-Authenticate realm in docker_pull module

The dockerpull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation.

gnutls: gnutls: Security bypass due to incorrect name constraint handling

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...
