Out-of-Bounds SNYK-DEBIAN8-LIBBSD-371223

by ADMIN 41 views

Introduction

The libbsd library is a collection of functions that provide a portable way to access various system services. However, a critical vulnerability was discovered in the fgetwln function of libbsd, which allows attackers to have unspecified impact via unknown vectors, triggering a heap-based buffer overflow. This vulnerability, known as SNYK-DEBIAN8-LIBBSD-371223, affects Debian 8 and has been assigned the CVE-2016-2090 identifier.

Vulnerability Details

The fgetwln function in libbsd before version 0.8.2 is vulnerable to a heap-based buffer overflow attack. This vulnerability allows attackers to execute arbitrary code on the system, potentially leading to a complete compromise of the system's security. The vulnerability is caused by a flaw in the way the fgetwln function handles input data, which can lead to a buffer overflow.

Impact

The impact of this vulnerability is significant, as it allows attackers to execute arbitrary code on the system. This can lead to a complete compromise of the system's security, potentially resulting in data theft, system compromise, or other malicious activities.

Remediation

To remediate this vulnerability, users are advised to upgrade their libbsd package to version 0.7.0-2+deb8u1 or higher. This will ensure that the vulnerable fgetwln function is replaced with a secure version, preventing attackers from exploiting the vulnerability.
