github.com/expr-lang/expr: Memory Exhaustion in Expr Parser with Unrestricted Input

A flaw was found in Expr. This vulnerability allows excessive memory usage and potential out-of-memory OOM crashes via unbounded input strings, where a malicious or inadvertent large expression can cause the parser to construct an extremely large Abstract Syntax Tree AST, consuming excessive memo...

ROS-20250403-04

A vulnerability in the Go programming language is related to improper syntax correctness checking of input. Exploitation of the vulnerability allows an attacker acting remotely to cause a denial of service...

USN-7404-1 phpseclib vulnerabilities

It was discovered that phpseclib did not correctly handle RSA PKCS1 v1.5 signature verification. An attacker could possibly use this issue to bypass authentication. This issue only affected Ubuntu 20.04 LTS. CVE-2021-30130 It was discovered that phpseclib did not correctly handle certain characte...

The vulnerability of the Go programming language lies in the improper checking of syntax correctness in input, which allows attackers to trigger service failures.

RHEL 8 : postgresql:12 (RHSA-2025:3064)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:3064 advisory. PostgreSQL is an advanced object-relational database management system DBMS. Security Fixes: postgresql: PostgreSQL quoting APIs miss neutralizing...

postgresql: PostgreSQL quoting APIs miss neutralizing quoting syntax in text that fails encoding validation

A flaw was found in PostgreSQL. Due to improper neutralization of quoting syntax, affected versions potentially allow a database input provider to achieve SQL injection in certain usage patterns. Specifically, SQL injection requires the application to use the affected function's result to constru...

H2O 资源管理错误漏洞

H2O is an in-memory platform for distributed, scalable machine learning open-sourced by H2O.ai. A resource management error vulnerability exists in H2O version 3.46.0.1, which stems from the runtool command exposing classes in the water.tools package via the ast parser, which could lead to a deni...

Memory Exhaustion in Expr Parser with Unrestricted Input

Impact If the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree AST node for each part of the expression. In scenarios where input size isn’t limited, a malicious or inadvertent extremely large expression c...

CVE-2025-29786

A flaw was found in Expr. This vulnerability allows excessive memory usage and potential out-of-memory OOM crashes via unbounded input strings, where a malicious or inadvertent large expression can cause the parser to construct an extremely large Abstract Syntax Tree AST, consuming excessive...

DEBIAN-CVE-2025-29786

Expr is an expression language and expression evaluation for Go. Prior to version 1.17.0, if the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree AST node for each part of the expression. In scenarios wher...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the parseExpression function in parser.go, due to the unrestricted size of input strings, which can cause the generation of large Abstract Syntax Trees ASTs. An attacker can crash...

CVE-2025-29786

CVE-2025-29786 concerns the Expr expression parser (Go). Prior to 1.17.0, unbounded input can cause the parser to build an excessively large AST, leading to high memory usage or an OOM crash. The issue is mitigated by a patch in 1.17.0 that enforces node budget and memory limits during parsing. R...
