postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

Important: Red Hat Security Advisory: postgresql:12 security update

An update for the postgresql:12 module is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A...

postgresql: PostgreSQL: Arbitrary code execution via logical decoding plugin

A flaw was found in PostgreSQL. Missing authorization in PostgreSQL's logical decoding feature allows a non-superuser with REPLICATION privilege to load arbitrary files. This can lead to arbitrary code execution as the operating system account running the server...

postgresql: PostgreSQL: Arbitrary code execution via type confusion in 'refint' module

A flaw was found in PostgreSQL. A type confusion vulnerability in the 'refint' module allows an object creator to execute arbitrary code as the operating system user running the database. This could lead to a complete compromise of the database server...

postgresql: pltcl: plperl: PostgreSQL: Arbitrary code execution in 32-bit pltcl and plperl

A flaw was found in PostgreSQL. An integer wraparound vulnerability in 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This can lead to arbitrary code execution as the operating system...

postgresql: PostgreSQL: Arbitrary code execution via type confusion with "internal" arguments

A type confusion vulnerability in PostgreSQL allows any user to execute arbitrary code as the database's operating system user by calling functions with mishandled "internal" data type arguments...

USN-8852-1 openvpn vulnerabilities

It was discovered that OpenVPN had a use-after-free vulnerability in its TLS session handling. An attacker could possibly use this issue to cause OpenVPN to crash, resulting in a denial of service, or execute arbitrary code. CVE-2026-84471 It was discovered that OpenVPN incorrectly handled...

USN-8852-1: OpenVPN vulnerabilities

It was discovered that OpenVPN had a use-after-free vulnerability in its TLS session handling. An attacker could possibly use this issue to cause OpenVPN to crash, resulting in a denial of service, or execute arbitrary code. CVE-2026-84471 It was discovered that OpenVPN incorrectly handled...

CVE-2026-92957

A flaw was found in vm2. Untrusted code running within the sandbox can bypass module restriction policies to achieve arbitrary code execution on the underlying host. Due to improper normalization of module names containing the node: prefix, deny-list rules fail to prevent access to sensitive...

CVE-2026-92956

A flaw was found in vm2. When running untrusted code within a sandbox, improper isolation in WebAssembly streaming functions allows host error objects to leak into the sandbox environment. An attacker capable of running code inside the sandbox can exploit this flaw to escape sandbox containment a...

CVE-2026-92951

A flaw was found in vm2. The external package allowlist improperly validates package names using substring matching rather than exact name boundaries. An attacker capable of running code within the sandbox can exploit this issue by requesting a package name containing an allowlisted substring,...

CVE-2026-92950

A flaw was found in vm2. An attacker can achieve arbitrary code execution on the host system by escaping sandbox isolation through the command-line interface CLI tool. By supplying a malicious script that uses the require function to re-execute itself within the host environment, untrusted code c...

CVE-2026-92946

A flaw was found in vm2. This vulnerability allows an attacker executing untrusted code within the sandbox to escape isolation and achieve arbitrary code execution on the host system. When external module loading is permitted without restricting access to dependency directories, sandboxed code ca...

CVE-2026-92944

A flaw was found in vm2. An attacker capable of running code within the sandbox environment can bypass security wrappers by supplying a crafted asynchronous Promise object. This flaw allows the attacker to escape the sandbox and access host system objects, leading to arbitrary code execution on t...

CVE-2026-92939

A flaw was found in vm2. When the cryptographic built-in module is enabled, functions exposed to the sandbox continue to run with the privileges of the host process. An attacker capable of running untrusted code within the sandbox can invoke the crypto.setEngine function to load a malicious local...

CVE-2026-92938

A flaw was found in vm2. Untrusted code running within the sandbox environment can bypass isolation restrictions when the host SQLite module is accessible. By crafting module import requests and loading native database extensions, an attacker can escape the sandbox and achieve arbitrary code...

CVE-2026-92937

A flaw was found in vm2. This vulnerability allows an attacker to escape the sandbox environment and achieve arbitrary code execution on the host system. The issue occurs because the sandbox bridge fails to properly sanitize rejected Promise errors when handlers are registered through indirect...

CVE-2026-92934

A flaw was found in vm2. A remote attacker able to run code within the sandbox can bypass environment isolation by exploiting an error handling flaw that fails to properly sanitize host objects. By accessing these unprotected host objects, an attacker can achieve arbitrary code execution and acce...

CVE-2026-92935

A flaw was found in vm2. This vulnerability allows an attacker who can execute untrusted JavaScript inside the sandbox to achieve arbitrary code execution on the host system. By providing an array value to the require configuration when nested sandboxes are enabled, the attacker can bypass...

CVE-2026-92948

A flaw was found in vm2. This vulnerability allows an attacker with permission to run code inside the sandbox to escape containment and achieve arbitrary code execution on the host system. Due to improper validation of built-in module names, the sandbox fails to block access to sensitive host...
