CVE-2025-64331
Description
A flaw was found in Suricata. This vulnerability allows a stack overflow, leading to a denial of service (DoS), via large HTTP (Hypertext Transfer Protocol) file transfers when the HTTP (Hypertext Transfer Protocol) response body limit is increased and logging of printable HTTP (Hypertext Transfer Protocol) bodies is enabled.
Statement
The highest threat is to system availability. This issue only affects systems where Suricata is configured with an increased HTTP response body limit and has logging of printable HTTP bodies enabled, which is a non-default configuration.
Understanding the Weakness (CWE)
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
Integrity,Confidentiality,Availability,Access Control
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy.
Integrity,Confidentiality,Availability,Access Control,Other
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism; Other
When the consequence is arbitrary code execution, this can often be used to subvert any other security service.
