Описание
Browserslist is a configuration tool for sharing target browsers and Node.js versions between front-end tools. Prior to 4.28.7, index.js retains every distinct (queries, context) result in cache and every parseQueries() AST in parseCache without a size cap, TTL, or eviction, allowing an attacker who can influence repeated browserslist() query values, including valid since <year>-<month>-<day> queries, to bypass the caller-controlled BROWSERSLIST_DISABLE_CACHE mitigation and cause linear memory growth followed by an out-of-memory process crash. This issue is fixed in version 4.28.7.
A flaw was found in Browserslist, a configuration tool for front-end development. An attacker can exploit this vulnerability by influencing repeated query values, leading to unbounded memory growth. This issue can cause the application to consume excessive memory, resulting in an out-of-memory process crash and a Denial of Service (DoS) for affected systems.
Отчет
This is an Important denial of service vulnerability in the browserslist library, which is used across several Red Hat products and services. The flaw allows an attacker to trigger unbounded memory growth by influencing query values, potentially leading to an out-of-memory crash and service unavailability. This is considered Important due to the potential for remote exploitation and significant impact on service stability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
