Описание
The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.20, 2.1.6, 3.0.8, and 5.0.11, deeply nested brace groups cause expand_() to recurse once per nesting level at comma-member and single-set expansion sites, exhausting the native stack before output limits can apply and potentially terminating the Node.js process. expand_ performs uncontrolled recursion for nested brace alternatives and single-part sets. deeply nested brace groups supplied as an untrusted pattern. expand_ is affected. expand is affected. Comma members is affected. Single set is affected. native stack exhaustion during nested sub-expansion. process-terminating denial of service. This issue is fixed in versions 1.1.20, 2.1.6, 3.0.8, and 5.0.11.
A flaw was found in brace-expansion. A remote attacker can cause a Denial of Service (DoS) by supplying untrusted input containing deeply nested brace patterns. Due to uncontrolled recursion during pattern processing, expanding these nested structures exhausts the call stack and causes the application to crash.
Отчет
This vulnerability is rated as Important because remote unauthenticated attackers can supply crafted nested expressions to trigger native stack exhaustion and crash server-side processes, resulting in a denial of service without compromising system confidentiality or integrity. In Red Hat environments, the affected library is distributed across containerized web consoles, developer tools, and Node.js runtime environments. Exploitation is constrained to deployments where applications process untrusted, user-defined pattern inputs directly through expansion functions without input depth validation.
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.
