Welcome to our Linux security focus, where we diligently inform and update our readers—especially users and administrators of Linux systems—about significant security vulnerabilities. Today, we spotlight a recently identified issue tagged as CVE-2023-49991, which impacts the text-to-speech software Espeak-ng, specifically version 1.52-dev.
Espeak-ng is an open-source, compact speech synthesizer software for English and other languages, designed for Linux and other operating systems. It converts text to audible speech and is particularly useful for accessibility (aiding those with visual impairments) and automated voice prompts in applications.
This vulnerability, categorized with a severity of medium and a score of 5.3, has been identified as a Stack Buffer Underflow in the function CountVowelPosition located in the file synthdata.c. A stack buffer underflow can occur when a program writes to a memory location before the start of a buffer, which leads to unexpected behavior including crashes, data corruption, or potential execution of malicious code.
The presence of this vulnerability in Espeak-ng means attackers can craft specific inputs that trigger the buffer underflow, leading to the aforementioned adverse effects. Systems using the 1.52-dev version of Espeak-ng may be susceptible to targeted attacks that exploit this weakness, compromising system stability and security.
Ensuring your system's security involves a timely response once a vulnerability has been publicized. The first step is to verify if your system uses the affected version of Espeak-ng. If it does, the next logical step is to seek and apply patches that resolve this issue. Developers often release fixes swiftly after vulnerabilities like these are uncovered.
